HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 278, 674 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 278, 674 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 278, 674 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 278, 674 is 2.

HCF(278, 674) = 2

HCF of 278, 674 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 278, 674 is 2.

Highest Common Factor of 278,674 using Euclid's algorithm

Highest Common Factor of 278,674 is 2

Step 1: Since 674 > 278, we apply the division lemma to 674 and 278, to get

674 = 278 x 2 + 118

Step 2: Since the reminder 278 ≠ 0, we apply division lemma to 118 and 278, to get

278 = 118 x 2 + 42

Step 3: We consider the new divisor 118 and the new remainder 42, and apply the division lemma to get

118 = 42 x 2 + 34

We consider the new divisor 42 and the new remainder 34,and apply the division lemma to get

42 = 34 x 1 + 8

We consider the new divisor 34 and the new remainder 8,and apply the division lemma to get

34 = 8 x 4 + 2

We consider the new divisor 8 and the new remainder 2,and apply the division lemma to get

8 = 2 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 278 and 674 is 2

Notice that 2 = HCF(8,2) = HCF(34,8) = HCF(42,34) = HCF(118,42) = HCF(278,118) = HCF(674,278) .
