HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 677, 3097, 1653 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 677, 3097, 1653 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 677, 3097, 1653 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 677, 3097, 1653 is 1.

HCF(677, 3097, 1653) = 1

Highest common factor (HCF) of 677, 3097, 1653 is 1.

Highest Common Factor of 677,3097,1653 using Euclid's algorithm

Highest Common Factor of 677,3097,1653 is 1

Step 1: Since 3097 > 677, we apply the division lemma to 3097 and 677, to get

3097 = 677 x 4 + 389

Step 2: Since the reminder 677 ≠ 0, we apply division lemma to 389 and 677, to get

677 = 389 x 1 + 288

Step 3: We consider the new divisor 389 and the new remainder 288, and apply the division lemma to get

389 = 288 x 1 + 101

We consider the new divisor 288 and the new remainder 101,and apply the division lemma to get

288 = 101 x 2 + 86

We consider the new divisor 101 and the new remainder 86,and apply the division lemma to get

101 = 86 x 1 + 15

We consider the new divisor 86 and the new remainder 15,and apply the division lemma to get

86 = 15 x 5 + 11

We consider the new divisor 15 and the new remainder 11,and apply the division lemma to get

15 = 11 x 1 + 4

We consider the new divisor 11 and the new remainder 4,and apply the division lemma to get

11 = 4 x 2 + 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 677 and 3097 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(11,4) = HCF(15,11) = HCF(86,15) = HCF(101,86) = HCF(288,101) = HCF(389,288) = HCF(677,389) = HCF(3097,677) .

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

Step 1: Since 1653 > 1, we apply the division lemma to 1653 and 1, to get

1653 = 1 x 1653 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 1653 is 1

Notice that 1 = HCF(1653,1) .
