HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 609, 805, 855, 76 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 609, 805, 855, 76 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 609, 805, 855, 76 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 609, 805, 855, 76 is 1.
HCF(609, 805, 855, 76) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 609, 805, 855, 76 is 1.
Step 1: Since 805 > 609, we apply the division lemma to 805 and 609, to get
805 = 609 x 1 + 196
Step 2: Since the reminder 609 ≠ 0, we apply division lemma to 196 and 609, to get
609 = 196 x 3 + 21
Step 3: We consider the new divisor 196 and the new remainder 21, and apply the division lemma to get
196 = 21 x 9 + 7
We consider the new divisor 21 and the new remainder 7, and apply the division lemma to get
21 = 7 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 609 and 805 is 7
Notice that 7 = HCF(21,7) = HCF(196,21) = HCF(609,196) = HCF(805,609) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 855 > 7, we apply the division lemma to 855 and 7, to get
855 = 7 x 122 + 1
Step 2: Since the reminder 7 ≠ 0, we apply division lemma to 1 and 7, to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 7 and 855 is 1
Notice that 1 = HCF(7,1) = HCF(855,7) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 76 > 1, we apply the division lemma to 76 and 1, to get
76 = 1 x 76 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 76 is 1
Notice that 1 = HCF(76,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 609, 805, 855, 76?
Answer: HCF of 609, 805, 855, 76 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 609, 805, 855, 76 using Euclid's Algorithm?
Answer: For arbitrary numbers 609, 805, 855, 76 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
