HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 615, 864, 477 i.e. 3 the largest integer that leaves a remainder zero for all numbers.

HCF of 615, 864, 477 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 615, 864, 477 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 615, 864, 477 is 3.

HCF(615, 864, 477) = 3

HCF of 615, 864, 477 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 615, 864, 477 is 3.

Highest Common Factor of 615,864,477 using Euclid's algorithm

Highest Common Factor of 615,864,477 is 3

Step 1: Since 864 > 615, we apply the division lemma to 864 and 615, to get

864 = 615 x 1 + 249

Step 2: Since the reminder 615 ≠ 0, we apply division lemma to 249 and 615, to get

615 = 249 x 2 + 117

Step 3: We consider the new divisor 249 and the new remainder 117, and apply the division lemma to get

249 = 117 x 2 + 15

We consider the new divisor 117 and the new remainder 15,and apply the division lemma to get

117 = 15 x 7 + 12

We consider the new divisor 15 and the new remainder 12,and apply the division lemma to get

15 = 12 x 1 + 3

We consider the new divisor 12 and the new remainder 3,and apply the division lemma to get

12 = 3 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 615 and 864 is 3

Notice that 3 = HCF(12,3) = HCF(15,12) = HCF(117,15) = HCF(249,117) = HCF(615,249) = HCF(864,615) .


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

Step 1: Since 477 > 3, we apply the division lemma to 477 and 3, to get

477 = 3 x 159 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 477 is 3

Notice that 3 = HCF(477,3) .
