HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 715, 639, 10 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 715, 639, 10 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 715, 639, 10 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 715, 639, 10 is 1.

HCF(715, 639, 10) = 1

HCF of 715, 639, 10 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 715, 639, 10 is 1.

Highest Common Factor of 715,639,10 using Euclid's algorithm

Highest Common Factor of 715,639,10 is 1

Step 1: Since 715 > 639, we apply the division lemma to 715 and 639, to get

715 = 639 x 1 + 76

Step 2: Since the reminder 639 ≠ 0, we apply division lemma to 76 and 639, to get

639 = 76 x 8 + 31

Step 3: We consider the new divisor 76 and the new remainder 31, and apply the division lemma to get

76 = 31 x 2 + 14

We consider the new divisor 31 and the new remainder 14,and apply the division lemma to get

31 = 14 x 2 + 3

We consider the new divisor 14 and the new remainder 3,and apply the division lemma to get

14 = 3 x 4 + 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 715 and 639 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(14,3) = HCF(31,14) = HCF(76,31) = HCF(639,76) = HCF(715,639) .

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

Step 1: Since 10 > 1, we apply the division lemma to 10 and 1, to get

10 = 1 x 10 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 10 is 1

Notice that 1 = HCF(10,1) .
