HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 275, 706, 639 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 275, 706, 639 is 1 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 275, 706, 639 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 275, 706, 639 is 1.

HCF(275, 706, 639) = 1

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

HCF of:

Highest common factor (HCF) of 275, 706, 639 is 1.

Highest Common Factor of 275,706,639 using Euclid's algorithm

Highest Common Factor of 275,706,639 is 1

Step 1: Since 706 > 275, we apply the division lemma to 706 and 275, to get

706 = 275 x 2 + 156

Step 2: Since the reminder 275 ≠ 0, we apply division lemma to 156 and 275, to get

275 = 156 x 1 + 119

Step 3: We consider the new divisor 156 and the new remainder 119, and apply the division lemma to get

156 = 119 x 1 + 37

We consider the new divisor 119 and the new remainder 37,and apply the division lemma to get

119 = 37 x 3 + 8

We consider the new divisor 37 and the new remainder 8,and apply the division lemma to get

37 = 8 x 4 + 5

We consider the new divisor 8 and the new remainder 5,and apply the division lemma to get

8 = 5 x 1 + 3

We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get

5 = 3 x 1 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 275 and 706 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(37,8) = HCF(119,37) = HCF(156,119) = HCF(275,156) = HCF(706,275) .

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

Step 1: Since 639 > 1, we apply the division lemma to 639 and 1, to get

639 = 1 x 639 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 639 is 1

Notice that 1 = HCF(639,1) .
