HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 355, 692, 631 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 355, 692, 631 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 355, 692, 631 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 355, 692, 631 is 1.

HCF(355, 692, 631) = 1

Highest common factor (HCF) of 355, 692, 631 is 1.

Highest Common Factor of 355,692,631 using Euclid's algorithm

Highest Common Factor of 355,692,631 is 1

Step 1: Since 692 > 355, we apply the division lemma to 692 and 355, to get

692 = 355 x 1 + 337

Step 2: Since the reminder 355 ≠ 0, we apply division lemma to 337 and 355, to get

355 = 337 x 1 + 18

Step 3: We consider the new divisor 337 and the new remainder 18, and apply the division lemma to get

337 = 18 x 18 + 13

We consider the new divisor 18 and the new remainder 13,and apply the division lemma to get

18 = 13 x 1 + 5

We consider the new divisor 13 and the new remainder 5,and apply the division lemma to get

13 = 5 x 2 + 3

We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get

5 = 3 x 1 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 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 355 and 692 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(13,5) = HCF(18,13) = HCF(337,18) = HCF(355,337) = HCF(692,355) .

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

Step 1: Since 631 > 1, we apply the division lemma to 631 and 1, to get

631 = 1 x 631 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 631 is 1

Notice that 1 = HCF(631,1) .
