HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 65, 473 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 65, 473 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 65, 473 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 65, 473 is 1.

HCF(65, 473) = 1

## HCF of 65, 473 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 65, 473 is 1. ### Highest Common Factor of 65,473 is 1

Step 1: Since 473 > 65, we apply the division lemma to 473 and 65, to get

473 = 65 x 7 + 18

Step 2: Since the reminder 65 ≠ 0, we apply division lemma to 18 and 65, to get

65 = 18 x 3 + 11

Step 3: We consider the new divisor 18 and the new remainder 11, and apply the division lemma to get

18 = 11 x 1 + 7

We consider the new divisor 11 and the new remainder 7,and apply the division lemma to get

11 = 7 x 1 + 4

We consider the new divisor 7 and the new remainder 4,and apply the division lemma to get

7 = 4 x 1 + 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 65 and 473 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(11,7) = HCF(18,11) = HCF(65,18) = HCF(473,65) .
