HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 916, 607, 420 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 916, 607, 420 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 916, 607, 420 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 916, 607, 420 is 1.

HCF(916, 607, 420) = 1

HCF of 916, 607, 420 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 916, 607, 420 is 1.

Highest Common Factor of 916,607,420 using Euclid's algorithm

Highest Common Factor of 916,607,420 is 1

Step 1: Since 916 > 607, we apply the division lemma to 916 and 607, to get

916 = 607 x 1 + 309

Step 2: Since the reminder 607 ≠ 0, we apply division lemma to 309 and 607, to get

607 = 309 x 1 + 298

Step 3: We consider the new divisor 309 and the new remainder 298, and apply the division lemma to get

309 = 298 x 1 + 11

We consider the new divisor 298 and the new remainder 11,and apply the division lemma to get

298 = 11 x 27 + 1

We consider the new divisor 11 and the new remainder 1,and apply the division lemma to get

11 = 1 x 11 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 916 and 607 is 1

Notice that 1 = HCF(11,1) = HCF(298,11) = HCF(309,298) = HCF(607,309) = HCF(916,607) .


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

Step 1: Since 420 > 1, we apply the division lemma to 420 and 1, to get

420 = 1 x 420 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 420 is 1

Notice that 1 = HCF(420,1) .
