HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 418, 712, 872 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 418, 712, 872 is 2 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 418, 712, 872 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 418, 712, 872 is 2.

HCF(418, 712, 872) = 2

HCF of 418, 712, 872 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

Highest common factor (HCF) of 418, 712, 872 is 2.

Highest Common Factor of 418,712,872 using Euclid's algorithm

Highest Common Factor of 418,712,872 is 2

Step 1: Since 712 > 418, we apply the division lemma to 712 and 418, to get

712 = 418 x 1 + 294

Step 2: Since the reminder 418 ≠ 0, we apply division lemma to 294 and 418, to get

418 = 294 x 1 + 124

Step 3: We consider the new divisor 294 and the new remainder 124, and apply the division lemma to get

294 = 124 x 2 + 46

We consider the new divisor 124 and the new remainder 46,and apply the division lemma to get

124 = 46 x 2 + 32

We consider the new divisor 46 and the new remainder 32,and apply the division lemma to get

46 = 32 x 1 + 14

We consider the new divisor 32 and the new remainder 14,and apply the division lemma to get

32 = 14 x 2 + 4

We consider the new divisor 14 and the new remainder 4,and apply the division lemma to get

14 = 4 x 3 + 2

We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get

4 = 2 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 418 and 712 is 2

Notice that 2 = HCF(4,2) = HCF(14,4) = HCF(32,14) = HCF(46,32) = HCF(124,46) = HCF(294,124) = HCF(418,294) = HCF(712,418) .

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

Step 1: Since 872 > 2, we apply the division lemma to 872 and 2, to get

872 = 2 x 436 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 872 is 2

Notice that 2 = HCF(872,2) .
