HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 857, 722, 756 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 857, 722, 756 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 857, 722, 756 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 857, 722, 756 is 1.

HCF(857, 722, 756) = 1

Highest common factor (HCF) of 857, 722, 756 is 1.

Highest Common Factor of 857,722,756 using Euclid's algorithm

Highest Common Factor of 857,722,756 is 1

Step 1: Since 857 > 722, we apply the division lemma to 857 and 722, to get

857 = 722 x 1 + 135

Step 2: Since the reminder 722 ≠ 0, we apply division lemma to 135 and 722, to get

722 = 135 x 5 + 47

Step 3: We consider the new divisor 135 and the new remainder 47, and apply the division lemma to get

135 = 47 x 2 + 41

We consider the new divisor 47 and the new remainder 41,and apply the division lemma to get

47 = 41 x 1 + 6

We consider the new divisor 41 and the new remainder 6,and apply the division lemma to get

41 = 6 x 6 + 5

We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get

6 = 5 x 1 + 1

We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get

5 = 1 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 857 and 722 is 1

Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(41,6) = HCF(47,41) = HCF(135,47) = HCF(722,135) = HCF(857,722) .


We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 756 > 1, we apply the division lemma to 756 and 1, to get

756 = 1 x 756 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 756 is 1

Notice that 1 = HCF(756,1) .
