HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 70, 611, 126, 637 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 70, 611, 126, 637 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 70, 611, 126, 637 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 70, 611, 126, 637 is 1.

HCF(70, 611, 126, 637) = 1

HCF of 70, 611, 126, 637 using Euclid's algorithm

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

Highest common factor (HCF) of 70, 611, 126, 637 is 1.

Highest Common Factor of 70,611,126,637 using Euclid's algorithm

Highest Common Factor of 70,611,126,637 is 1

Step 1: Since 611 > 70, we apply the division lemma to 611 and 70, to get

611 = 70 x 8 + 51

Step 2: Since the reminder 70 ≠ 0, we apply division lemma to 51 and 70, to get

70 = 51 x 1 + 19

Step 3: We consider the new divisor 51 and the new remainder 19, and apply the division lemma to get

51 = 19 x 2 + 13

We consider the new divisor 19 and the new remainder 13,and apply the division lemma to get

19 = 13 x 1 + 6

We consider the new divisor 13 and the new remainder 6,and apply the division lemma to get

13 = 6 x 2 + 1

We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get

6 = 1 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 70 and 611 is 1

Notice that 1 = HCF(6,1) = HCF(13,6) = HCF(19,13) = HCF(51,19) = HCF(70,51) = HCF(611,70) .

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

Step 1: Since 126 > 1, we apply the division lemma to 126 and 1, to get

126 = 1 x 126 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 126 is 1

Notice that 1 = HCF(126,1) .

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

Step 1: Since 637 > 1, we apply the division lemma to 637 and 1, to get

637 = 1 x 637 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 637 is 1

Notice that 1 = HCF(637,1) .
