HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 91, 975 i.e. 13 the largest integer that leaves a remainder zero for all numbers.

HCF of 91, 975 is 13 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 91, 975 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 91, 975 is 13.

HCF(91, 975) = 13

HCF of 91, 975 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 91, 975 is 13.

Highest Common Factor of 91,975 using Euclid's algorithm

Highest Common Factor of 91,975 is 13

Step 1: Since 975 > 91, we apply the division lemma to 975 and 91, to get

975 = 91 x 10 + 65

Step 2: Since the reminder 91 ≠ 0, we apply division lemma to 65 and 91, to get

91 = 65 x 1 + 26

Step 3: We consider the new divisor 65 and the new remainder 26, and apply the division lemma to get

65 = 26 x 2 + 13

We consider the new divisor 26 and the new remainder 13, and apply the division lemma to get

26 = 13 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 13, the HCF of 91 and 975 is 13

Notice that 13 = HCF(26,13) = HCF(65,26) = HCF(91,65) = HCF(975,91) .
