HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 422, 756 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 422, 756 is 2 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 422, 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 422, 756 is 2.

HCF(422, 756) = 2

Highest common factor (HCF) of 422, 756 is 2.

Highest Common Factor of 422,756 using Euclid's algorithm

Highest Common Factor of 422,756 is 2

Step 1: Since 756 > 422, we apply the division lemma to 756 and 422, to get

756 = 422 x 1 + 334

Step 2: Since the reminder 422 ≠ 0, we apply division lemma to 334 and 422, to get

422 = 334 x 1 + 88

Step 3: We consider the new divisor 334 and the new remainder 88, and apply the division lemma to get

334 = 88 x 3 + 70

We consider the new divisor 88 and the new remainder 70,and apply the division lemma to get

88 = 70 x 1 + 18

We consider the new divisor 70 and the new remainder 18,and apply the division lemma to get

70 = 18 x 3 + 16

We consider the new divisor 18 and the new remainder 16,and apply the division lemma to get

18 = 16 x 1 + 2

We consider the new divisor 16 and the new remainder 2,and apply the division lemma to get

16 = 2 x 8 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 422 and 756 is 2

Notice that 2 = HCF(16,2) = HCF(18,16) = HCF(70,18) = HCF(88,70) = HCF(334,88) = HCF(422,334) = HCF(756,422) .
