HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 397, 625 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 397, 625 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 397, 625 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 397, 625 is 1.

HCF(397, 625) = 1

Highest common factor (HCF) of 397, 625 is 1.

Highest Common Factor of 397,625 using Euclid's algorithm

Highest Common Factor of 397,625 is 1

Step 1: Since 625 > 397, we apply the division lemma to 625 and 397, to get

625 = 397 x 1 + 228

Step 2: Since the reminder 397 ≠ 0, we apply division lemma to 228 and 397, to get

397 = 228 x 1 + 169

Step 3: We consider the new divisor 228 and the new remainder 169, and apply the division lemma to get

228 = 169 x 1 + 59

We consider the new divisor 169 and the new remainder 59,and apply the division lemma to get

169 = 59 x 2 + 51

We consider the new divisor 59 and the new remainder 51,and apply the division lemma to get

59 = 51 x 1 + 8

We consider the new divisor 51 and the new remainder 8,and apply the division lemma to get

51 = 8 x 6 + 3

We consider the new divisor 8 and the new remainder 3,and apply the division lemma to get

8 = 3 x 2 + 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 397 and 625 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(8,3) = HCF(51,8) = HCF(59,51) = HCF(169,59) = HCF(228,169) = HCF(397,228) = HCF(625,397) .
