HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 490, 833, 605, 779 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 490, 833, 605, 779 is 1 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.
Consider we have numbers 490, 833, 605, 779 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b
Highest common factor (HCF) of 490, 833, 605, 779 is 1.
HCF(490, 833, 605, 779) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 490, 833, 605, 779 is 1.
Step 1: Since 833 > 490, we apply the division lemma to 833 and 490, to get
833 = 490 x 1 + 343
Step 2: Since the reminder 490 ≠ 0, we apply division lemma to 343 and 490, to get
490 = 343 x 1 + 147
Step 3: We consider the new divisor 343 and the new remainder 147, and apply the division lemma to get
343 = 147 x 2 + 49
We consider the new divisor 147 and the new remainder 49, and apply the division lemma to get
147 = 49 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 49, the HCF of 490 and 833 is 49
Notice that 49 = HCF(147,49) = HCF(343,147) = HCF(490,343) = HCF(833,490) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 605 > 49, we apply the division lemma to 605 and 49, to get
605 = 49 x 12 + 17
Step 2: Since the reminder 49 ≠ 0, we apply division lemma to 17 and 49, to get
49 = 17 x 2 + 15
Step 3: We consider the new divisor 17 and the new remainder 15, and apply the division lemma to get
17 = 15 x 1 + 2
We consider the new divisor 15 and the new remainder 2,and apply the division lemma to get
15 = 2 x 7 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 49 and 605 is 1
Notice that 1 = HCF(2,1) = HCF(15,2) = HCF(17,15) = HCF(49,17) = HCF(605,49) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 779 > 1, we apply the division lemma to 779 and 1, to get
779 = 1 x 779 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 779 is 1
Notice that 1 = HCF(779,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 490, 833, 605, 779?
Answer: HCF of 490, 833, 605, 779 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 490, 833, 605, 779 using Euclid's Algorithm?
Answer: For arbitrary numbers 490, 833, 605, 779 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
