# Highest Common Factor of 47, 45, 65 using Euclid's algorithm

HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 47, 45, 65 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 47, 45, 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 47, 45, 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 47, 45, 65 is 1.

HCF(47, 45, 65) = 1

## HCF of 47, 45, 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 47, 45, 65 is 1.

### Highest Common Factor of 47,45,65 using Euclid's algorithm

Step 1: Since 47 > 45, we apply the division lemma to 47 and 45, to get

47 = 45 x 1 + 2

Step 2: Since the reminder 45 ≠ 0, we apply division lemma to 2 and 45, to get

45 = 2 x 22 + 1

Step 3: 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 47 and 45 is 1

Notice that 1 = HCF(2,1) = HCF(45,2) = HCF(47,45) .

We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

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

65 = 1 x 65 + 0

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

Notice that 1 = HCF(65,1) .
