HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 422, 702, 956 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 422, 702, 956 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, 702, 956 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, 702, 956 is 2.

HCF(422, 702, 956) = 2

Highest common factor (HCF) of 422, 702, 956 is 2.

Highest Common Factor of 422,702,956 using Euclid's algorithm

Highest Common Factor of 422,702,956 is 2

Step 1: Since 702 > 422, we apply the division lemma to 702 and 422, to get

702 = 422 x 1 + 280

Step 2: Since the reminder 422 ≠ 0, we apply division lemma to 280 and 422, to get

422 = 280 x 1 + 142

Step 3: We consider the new divisor 280 and the new remainder 142, and apply the division lemma to get

280 = 142 x 1 + 138

We consider the new divisor 142 and the new remainder 138,and apply the division lemma to get

142 = 138 x 1 + 4

We consider the new divisor 138 and the new remainder 4,and apply the division lemma to get

138 = 4 x 34 + 2

We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get

4 = 2 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 422 and 702 is 2

Notice that 2 = HCF(4,2) = HCF(138,4) = HCF(142,138) = HCF(280,142) = HCF(422,280) = HCF(702,422) .

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

Step 1: Since 956 > 2, we apply the division lemma to 956 and 2, to get

956 = 2 x 478 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 956 is 2

Notice that 2 = HCF(956,2) .
