HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 620, 218 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 620, 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 620, 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 620, 218 is 2.

HCF(620, 218) = 2

HCF of 620, 218 using Euclid's algorithm

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

Highest common factor (HCF) of 620, 218 is 2.

Highest Common Factor of 620,218 using Euclid's algorithm

Highest Common Factor of 620,218 is 2

Step 1: Since 620 > 218, we apply the division lemma to 620 and 218, to get

620 = 218 x 2 + 184

Step 2: Since the reminder 218 ≠ 0, we apply division lemma to 184 and 218, to get

218 = 184 x 1 + 34

Step 3: We consider the new divisor 184 and the new remainder 34, and apply the division lemma to get

184 = 34 x 5 + 14

We consider the new divisor 34 and the new remainder 14,and apply the division lemma to get

34 = 14 x 2 + 6

We consider the new divisor 14 and the new remainder 6,and apply the division lemma to get

14 = 6 x 2 + 2

We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get

6 = 2 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 620 and 218 is 2

Notice that 2 = HCF(6,2) = HCF(14,6) = HCF(34,14) = HCF(184,34) = HCF(218,184) = HCF(620,218) .
