HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 605, 990, 622, 94 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 605, 990, 622, 94 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 605, 990, 622, 94 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 605, 990, 622, 94 is 1.
HCF(605, 990, 622, 94) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 605, 990, 622, 94 is 1.
Step 1: Since 990 > 605, we apply the division lemma to 990 and 605, to get
990 = 605 x 1 + 385
Step 2: Since the reminder 605 ≠ 0, we apply division lemma to 385 and 605, to get
605 = 385 x 1 + 220
Step 3: We consider the new divisor 385 and the new remainder 220, and apply the division lemma to get
385 = 220 x 1 + 165
We consider the new divisor 220 and the new remainder 165,and apply the division lemma to get
220 = 165 x 1 + 55
We consider the new divisor 165 and the new remainder 55,and apply the division lemma to get
165 = 55 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 55, the HCF of 605 and 990 is 55
Notice that 55 = HCF(165,55) = HCF(220,165) = HCF(385,220) = HCF(605,385) = HCF(990,605) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 622 > 55, we apply the division lemma to 622 and 55, to get
622 = 55 x 11 + 17
Step 2: Since the reminder 55 ≠ 0, we apply division lemma to 17 and 55, to get
55 = 17 x 3 + 4
Step 3: We consider the new divisor 17 and the new remainder 4, and apply the division lemma to get
17 = 4 x 4 + 1
We consider the new divisor 4 and the new remainder 1, and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 55 and 622 is 1
Notice that 1 = HCF(4,1) = HCF(17,4) = HCF(55,17) = HCF(622,55) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 94 > 1, we apply the division lemma to 94 and 1, to get
94 = 1 x 94 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 94 is 1
Notice that 1 = HCF(94,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
