HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 501, 630 i.e. 3 the largest integer that leaves a remainder zero for all numbers.

HCF of 501, 630 is 3 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 501, 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 501, 630 is 3.

HCF(501, 630) = 3

Highest Common Factor of 501,630 using Euclid's algorithm

Highest Common Factor of 501,630 is 3

Step 1: Since 630 > 501, we apply the division lemma to 630 and 501, to get

630 = 501 x 1 + 129

Step 2: Since the reminder 501 ≠ 0, we apply division lemma to 129 and 501, to get

501 = 129 x 3 + 114

Step 3: We consider the new divisor 129 and the new remainder 114, and apply the division lemma to get

129 = 114 x 1 + 15

We consider the new divisor 114 and the new remainder 15,and apply the division lemma to get

114 = 15 x 7 + 9

We consider the new divisor 15 and the new remainder 9,and apply the division lemma to get

15 = 9 x 1 + 6

We consider the new divisor 9 and the new remainder 6,and apply the division lemma to get

9 = 6 x 1 + 3

We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get

6 = 3 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 501 and 630 is 3

Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(15,9) = HCF(114,15) = HCF(129,114) = HCF(501,129) = HCF(630,501) .
