HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 252, 646, 278 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 252, 646, 278 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 252, 646, 278 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 252, 646, 278 is 2.

HCF(252, 646, 278) = 2

Highest Common Factor of 252,646,278 using Euclid's algorithm

Highest Common Factor of 252,646,278 is 2

Step 1: Since 646 > 252, we apply the division lemma to 646 and 252, to get

646 = 252 x 2 + 142

Step 2: Since the reminder 252 ≠ 0, we apply division lemma to 142 and 252, to get

252 = 142 x 1 + 110

Step 3: We consider the new divisor 142 and the new remainder 110, and apply the division lemma to get

142 = 110 x 1 + 32

We consider the new divisor 110 and the new remainder 32,and apply the division lemma to get

110 = 32 x 3 + 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 252 and 646 is 2

Notice that 2 = HCF(4,2) = HCF(14,4) = HCF(32,14) = HCF(110,32) = HCF(142,110) = HCF(252,142) = HCF(646,252) .

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

Step 1: Since 278 > 2, we apply the division lemma to 278 and 2, to get

278 = 2 x 139 + 0

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

Notice that 2 = HCF(278,2) .
