HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 615, 774, 707 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 615, 774, 707 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 615, 774, 707 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 615, 774, 707 is 1.

HCF(615, 774, 707) = 1

Highest Common Factor of 615,774,707 using Euclid's algorithm

Highest Common Factor of 615,774,707 is 1

Step 1: Since 774 > 615, we apply the division lemma to 774 and 615, to get

774 = 615 x 1 + 159

Step 2: Since the reminder 615 ≠ 0, we apply division lemma to 159 and 615, to get

615 = 159 x 3 + 138

Step 3: We consider the new divisor 159 and the new remainder 138, and apply the division lemma to get

159 = 138 x 1 + 21

We consider the new divisor 138 and the new remainder 21,and apply the division lemma to get

138 = 21 x 6 + 12

We consider the new divisor 21 and the new remainder 12,and apply the division lemma to get

21 = 12 x 1 + 9

We consider the new divisor 12 and the new remainder 9,and apply the division lemma to get

12 = 9 x 1 + 3

We consider the new divisor 9 and the new remainder 3,and apply the division lemma to get

9 = 3 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 615 and 774 is 3

Notice that 3 = HCF(9,3) = HCF(12,9) = HCF(21,12) = HCF(138,21) = HCF(159,138) = HCF(615,159) = HCF(774,615) .

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

Step 1: Since 707 > 3, we apply the division lemma to 707 and 3, to get

707 = 3 x 235 + 2

Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get

3 = 2 x 1 + 1

Step 3: 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 3 and 707 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(707,3) .
