HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 851, 724 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 851, 724 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 851, 724 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 851, 724 is 1.

HCF(851, 724) = 1

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

HCF of:

Highest common factor (HCF) of 851, 724 is 1.

Highest Common Factor of 851,724 using Euclid's algorithm

Highest Common Factor of 851,724 is 1

Step 1: Since 851 > 724, we apply the division lemma to 851 and 724, to get

851 = 724 x 1 + 127

Step 2: Since the reminder 724 ≠ 0, we apply division lemma to 127 and 724, to get

724 = 127 x 5 + 89

Step 3: We consider the new divisor 127 and the new remainder 89, and apply the division lemma to get

127 = 89 x 1 + 38

We consider the new divisor 89 and the new remainder 38,and apply the division lemma to get

89 = 38 x 2 + 13

We consider the new divisor 38 and the new remainder 13,and apply the division lemma to get

38 = 13 x 2 + 12

We consider the new divisor 13 and the new remainder 12,and apply the division lemma to get

13 = 12 x 1 + 1

We consider the new divisor 12 and the new remainder 1,and apply the division lemma to get

12 = 1 x 12 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 851 and 724 is 1

Notice that 1 = HCF(12,1) = HCF(13,12) = HCF(38,13) = HCF(89,38) = HCF(127,89) = HCF(724,127) = HCF(851,724) .
