HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 270, 736, 646 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 270, 736, 646 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 270, 736, 646 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 270, 736, 646 is 2.

HCF(270, 736, 646) = 2

Highest common factor (HCF) of 270, 736, 646 is 2.

Highest Common Factor of 270,736,646 using Euclid's algorithm

Highest Common Factor of 270,736,646 is 2

Step 1: Since 736 > 270, we apply the division lemma to 736 and 270, to get

736 = 270 x 2 + 196

Step 2: Since the reminder 270 ≠ 0, we apply division lemma to 196 and 270, to get

270 = 196 x 1 + 74

Step 3: We consider the new divisor 196 and the new remainder 74, and apply the division lemma to get

196 = 74 x 2 + 48

We consider the new divisor 74 and the new remainder 48,and apply the division lemma to get

74 = 48 x 1 + 26

We consider the new divisor 48 and the new remainder 26,and apply the division lemma to get

48 = 26 x 1 + 22

We consider the new divisor 26 and the new remainder 22,and apply the division lemma to get

26 = 22 x 1 + 4

We consider the new divisor 22 and the new remainder 4,and apply the division lemma to get

22 = 4 x 5 + 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 270 and 736 is 2

Notice that 2 = HCF(4,2) = HCF(22,4) = HCF(26,22) = HCF(48,26) = HCF(74,48) = HCF(196,74) = HCF(270,196) = HCF(736,270) .

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

Step 1: Since 646 > 2, we apply the division lemma to 646 and 2, to get

646 = 2 x 323 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 646 is 2

Notice that 2 = HCF(646,2) .
