HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 318, 556 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 318, 556 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 318, 556 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 318, 556 is 2.

HCF(318, 556) = 2

HCF of 318, 556 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 318, 556 is 2.

Highest Common Factor of 318,556 using Euclid's algorithm

Highest Common Factor of 318,556 is 2

Step 1: Since 556 > 318, we apply the division lemma to 556 and 318, to get

556 = 318 x 1 + 238

Step 2: Since the reminder 318 ≠ 0, we apply division lemma to 238 and 318, to get

318 = 238 x 1 + 80

Step 3: We consider the new divisor 238 and the new remainder 80, and apply the division lemma to get

238 = 80 x 2 + 78

We consider the new divisor 80 and the new remainder 78,and apply the division lemma to get

80 = 78 x 1 + 2

We consider the new divisor 78 and the new remainder 2,and apply the division lemma to get

78 = 2 x 39 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 318 and 556 is 2

Notice that 2 = HCF(78,2) = HCF(80,78) = HCF(238,80) = HCF(318,238) = HCF(556,318) .
