HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 974, 615 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 974, 615 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 974, 615 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 974, 615 is 1.

HCF(974, 615) = 1

Highest common factor (HCF) of 974, 615 is 1.

Highest Common Factor of 974,615 using Euclid's algorithm

Highest Common Factor of 974,615 is 1

Step 1: Since 974 > 615, we apply the division lemma to 974 and 615, to get

974 = 615 x 1 + 359

Step 2: Since the reminder 615 ≠ 0, we apply division lemma to 359 and 615, to get

615 = 359 x 1 + 256

Step 3: We consider the new divisor 359 and the new remainder 256, and apply the division lemma to get

359 = 256 x 1 + 103

We consider the new divisor 256 and the new remainder 103,and apply the division lemma to get

256 = 103 x 2 + 50

We consider the new divisor 103 and the new remainder 50,and apply the division lemma to get

103 = 50 x 2 + 3

We consider the new divisor 50 and the new remainder 3,and apply the division lemma to get

50 = 3 x 16 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 974 and 615 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(50,3) = HCF(103,50) = HCF(256,103) = HCF(359,256) = HCF(615,359) = HCF(974,615) .
