HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 636, 630 i.e. 6 the largest integer that leaves a remainder zero for all numbers.

HCF of 636, 630 is 6 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 636, 630 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 636, 630 is 6.

HCF(636, 630) = 6

HCF of 636, 630 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 636, 630 is 6.

Highest Common Factor of 636,630 using Euclid's algorithm

Highest Common Factor of 636,630 is 6

Step 1: Since 636 > 630, we apply the division lemma to 636 and 630, to get

636 = 630 x 1 + 6

Step 2: Since the reminder 630 ≠ 0, we apply division lemma to 6 and 630, to get

630 = 6 x 105 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 636 and 630 is 6

Notice that 6 = HCF(630,6) = HCF(636,630) .
