HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 718, 218 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 718, 218 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 718, 218 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 718, 218 is 2.

HCF(718, 218) = 2

HCF of 718, 218 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 718, 218 is 2.

Highest Common Factor of 718,218 using Euclid's algorithm

Highest Common Factor of 718,218 is 2

Step 1: Since 718 > 218, we apply the division lemma to 718 and 218, to get

718 = 218 x 3 + 64

Step 2: Since the reminder 218 ≠ 0, we apply division lemma to 64 and 218, to get

218 = 64 x 3 + 26

Step 3: We consider the new divisor 64 and the new remainder 26, and apply the division lemma to get

64 = 26 x 2 + 12

We consider the new divisor 26 and the new remainder 12,and apply the division lemma to get

26 = 12 x 2 + 2

We consider the new divisor 12 and the new remainder 2,and apply the division lemma to get

12 = 2 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 718 and 218 is 2

Notice that 2 = HCF(12,2) = HCF(26,12) = HCF(64,26) = HCF(218,64) = HCF(718,218) .
