HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 421, 952 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 421, 952 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 421, 952 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 421, 952 is 1.

HCF(421, 952) = 1

Highest common factor (HCF) of 421, 952 is 1.

Highest Common Factor of 421,952 using Euclid's algorithm

Highest Common Factor of 421,952 is 1

Step 1: Since 952 > 421, we apply the division lemma to 952 and 421, to get

952 = 421 x 2 + 110

Step 2: Since the reminder 421 ≠ 0, we apply division lemma to 110 and 421, to get

421 = 110 x 3 + 91

Step 3: We consider the new divisor 110 and the new remainder 91, and apply the division lemma to get

110 = 91 x 1 + 19

We consider the new divisor 91 and the new remainder 19,and apply the division lemma to get

91 = 19 x 4 + 15

We consider the new divisor 19 and the new remainder 15,and apply the division lemma to get

19 = 15 x 1 + 4

We consider the new divisor 15 and the new remainder 4,and apply the division lemma to get

15 = 4 x 3 + 3

We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get

4 = 3 x 1 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 421 and 952 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(15,4) = HCF(19,15) = HCF(91,19) = HCF(110,91) = HCF(421,110) = HCF(952,421) .
