HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 957, 373, 565 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 957, 373, 565 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, 373, 565 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, 373, 565 is 1.

HCF(957, 373, 565) = 1

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 957, 373, 565 is 1.

Highest Common Factor of 957,373,565 using Euclid's algorithm

Highest Common Factor of 957,373,565 is 1

Step 1: Since 957 > 373, we apply the division lemma to 957 and 373, to get

957 = 373 x 2 + 211

Step 2: Since the reminder 373 ≠ 0, we apply division lemma to 211 and 373, to get

373 = 211 x 1 + 162

Step 3: We consider the new divisor 211 and the new remainder 162, and apply the division lemma to get

211 = 162 x 1 + 49

We consider the new divisor 162 and the new remainder 49,and apply the division lemma to get

162 = 49 x 3 + 15

We consider the new divisor 49 and the new remainder 15,and apply the division lemma to get

49 = 15 x 3 + 4

We consider the new divisor 15 and the new remainder 4,and apply the division lemma to get

15 = 4 x 3 + 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 957 and 373 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(15,4) = HCF(49,15) = HCF(162,49) = HCF(211,162) = HCF(373,211) = HCF(957,373) .

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

Step 1: Since 565 > 1, we apply the division lemma to 565 and 1, to get

565 = 1 x 565 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 565 is 1

Notice that 1 = HCF(565,1) .
