HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 637, 578 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 637, 578 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 637, 578 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 637, 578 is 1.

HCF(637, 578) = 1

HCF of 637, 578 using Euclid's algorithm

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

HCF of:

Highest common factor (HCF) of 637, 578 is 1.

Highest Common Factor of 637,578 using Euclid's algorithm

Highest Common Factor of 637,578 is 1

Step 1: Since 637 > 578, we apply the division lemma to 637 and 578, to get

637 = 578 x 1 + 59

Step 2: Since the reminder 578 ≠ 0, we apply division lemma to 59 and 578, to get

578 = 59 x 9 + 47

Step 3: We consider the new divisor 59 and the new remainder 47, and apply the division lemma to get

59 = 47 x 1 + 12

We consider the new divisor 47 and the new remainder 12,and apply the division lemma to get

47 = 12 x 3 + 11

We consider the new divisor 12 and the new remainder 11,and apply the division lemma to get

12 = 11 x 1 + 1

We consider the new divisor 11 and the new remainder 1,and apply the division lemma to get

11 = 1 x 11 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 637 and 578 is 1

Notice that 1 = HCF(11,1) = HCF(12,11) = HCF(47,12) = HCF(59,47) = HCF(578,59) = HCF(637,578) .
