HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 657, 801, 371 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 657, 801, 371 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 657, 801, 371 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 657, 801, 371 is 1.

HCF(657, 801, 371) = 1

Highest common factor (HCF) of 657, 801, 371 is 1.

Highest Common Factor of 657,801,371 using Euclid's algorithm

Highest Common Factor of 657,801,371 is 1

Step 1: Since 801 > 657, we apply the division lemma to 801 and 657, to get

801 = 657 x 1 + 144

Step 2: Since the reminder 657 ≠ 0, we apply division lemma to 144 and 657, to get

657 = 144 x 4 + 81

Step 3: We consider the new divisor 144 and the new remainder 81, and apply the division lemma to get

144 = 81 x 1 + 63

We consider the new divisor 81 and the new remainder 63,and apply the division lemma to get

81 = 63 x 1 + 18

We consider the new divisor 63 and the new remainder 18,and apply the division lemma to get

63 = 18 x 3 + 9

We consider the new divisor 18 and the new remainder 9,and apply the division lemma to get

18 = 9 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 9, the HCF of 657 and 801 is 9

Notice that 9 = HCF(18,9) = HCF(63,18) = HCF(81,63) = HCF(144,81) = HCF(657,144) = HCF(801,657) .


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

Step 1: Since 371 > 9, we apply the division lemma to 371 and 9, to get

371 = 9 x 41 + 2

Step 2: Since the reminder 9 ≠ 0, we apply division lemma to 2 and 9, to get

9 = 2 x 4 + 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 9 and 371 is 1

Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(371,9) .
