HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 957, 455 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 957, 455 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 957, 455 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 957, 455 is 1.

HCF(957, 455) = 1

HCF of 957, 455 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 957, 455 is 1.

Highest Common Factor of 957,455 using Euclid's algorithm

Highest Common Factor of 957,455 is 1

Step 1: Since 957 > 455, we apply the division lemma to 957 and 455, to get

957 = 455 x 2 + 47

Step 2: Since the reminder 455 ≠ 0, we apply division lemma to 47 and 455, to get

455 = 47 x 9 + 32

Step 3: We consider the new divisor 47 and the new remainder 32, and apply the division lemma to get

47 = 32 x 1 + 15

We consider the new divisor 32 and the new remainder 15,and apply the division lemma to get

32 = 15 x 2 + 2

We consider the new divisor 15 and the new remainder 2,and apply the division lemma to get

15 = 2 x 7 + 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 957 and 455 is 1

Notice that 1 = HCF(2,1) = HCF(15,2) = HCF(32,15) = HCF(47,32) = HCF(455,47) = HCF(957,455) .
