HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 421, 535, 652 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 421, 535, 652 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, 535, 652 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, 535, 652 is 1.

HCF(421, 535, 652) = 1

Highest common factor (HCF) of 421, 535, 652 is 1.

Highest Common Factor of 421,535,652 using Euclid's algorithm

Highest Common Factor of 421,535,652 is 1

Step 1: Since 535 > 421, we apply the division lemma to 535 and 421, to get

535 = 421 x 1 + 114

Step 2: Since the reminder 421 ≠ 0, we apply division lemma to 114 and 421, to get

421 = 114 x 3 + 79

Step 3: We consider the new divisor 114 and the new remainder 79, and apply the division lemma to get

114 = 79 x 1 + 35

We consider the new divisor 79 and the new remainder 35,and apply the division lemma to get

79 = 35 x 2 + 9

We consider the new divisor 35 and the new remainder 9,and apply the division lemma to get

35 = 9 x 3 + 8

We consider the new divisor 9 and the new remainder 8,and apply the division lemma to get

9 = 8 x 1 + 1

We consider the new divisor 8 and the new remainder 1,and apply the division lemma to get

8 = 1 x 8 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 421 and 535 is 1

Notice that 1 = HCF(8,1) = HCF(9,8) = HCF(35,9) = HCF(79,35) = HCF(114,79) = HCF(421,114) = HCF(535,421) .

We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 652 > 1, we apply the division lemma to 652 and 1, to get

652 = 1 x 652 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 652 is 1

Notice that 1 = HCF(652,1) .
