HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 252, 921 i.e. 3 the largest integer that leaves a remainder zero for all numbers.

HCF of 252, 921 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 252, 921 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 252, 921 is 3.

HCF(252, 921) = 3

Highest Common Factor of 252,921 using Euclid's algorithm

Highest Common Factor of 252,921 is 3

Step 1: Since 921 > 252, we apply the division lemma to 921 and 252, to get

921 = 252 x 3 + 165

Step 2: Since the reminder 252 ≠ 0, we apply division lemma to 165 and 252, to get

252 = 165 x 1 + 87

Step 3: We consider the new divisor 165 and the new remainder 87, and apply the division lemma to get

165 = 87 x 1 + 78

We consider the new divisor 87 and the new remainder 78,and apply the division lemma to get

87 = 78 x 1 + 9

We consider the new divisor 78 and the new remainder 9,and apply the division lemma to get

78 = 9 x 8 + 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 252 and 921 is 3

Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(78,9) = HCF(87,78) = HCF(165,87) = HCF(252,165) = HCF(921,252) .
