HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 88, 65 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 88, 65 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 88, 65 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 88, 65 is 1.

HCF(88, 65) = 1

## HCF of 88, 65 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 88, 65 is 1. ### Highest Common Factor of 88,65 is 1

Step 1: Since 88 > 65, we apply the division lemma to 88 and 65, to get

88 = 65 x 1 + 23

Step 2: Since the reminder 65 ≠ 0, we apply division lemma to 23 and 65, to get

65 = 23 x 2 + 19

Step 3: We consider the new divisor 23 and the new remainder 19, and apply the division lemma to get

23 = 19 x 1 + 4

We consider the new divisor 19 and the new remainder 4,and apply the division lemma to get

19 = 4 x 4 + 3

We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get

4 = 3 x 1 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 88 and 65 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(19,4) = HCF(23,19) = HCF(65,23) = HCF(88,65) .
