HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 623, 637 i.e. 7 the largest integer that leaves a remainder zero for all numbers.

HCF of 623, 637 is 7 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 623, 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 623, 637 is 7.

HCF(623, 637) = 7

HCF of 623, 637 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 623, 637 is 7.

Highest Common Factor of 623,637 using Euclid's algorithm

Highest Common Factor of 623,637 is 7

Step 1: Since 637 > 623, we apply the division lemma to 637 and 623, to get

637 = 623 x 1 + 14

Step 2: Since the reminder 623 ≠ 0, we apply division lemma to 14 and 623, to get

623 = 14 x 44 + 7

Step 3: We consider the new divisor 14 and the new remainder 7, and apply the division lemma to get

14 = 7 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 623 and 637 is 7

Notice that 7 = HCF(14,7) = HCF(623,14) = HCF(637,623) .
