HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 640, 334, 156 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 640, 334, 156 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 640, 334, 156 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 640, 334, 156 is 2.

HCF(640, 334, 156) = 2

HCF of 640, 334, 156 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 640, 334, 156 is 2.

Highest Common Factor of 640,334,156 using Euclid's algorithm

Highest Common Factor of 640,334,156 is 2

Step 1: Since 640 > 334, we apply the division lemma to 640 and 334, to get

640 = 334 x 1 + 306

Step 2: Since the reminder 334 ≠ 0, we apply division lemma to 306 and 334, to get

334 = 306 x 1 + 28

Step 3: We consider the new divisor 306 and the new remainder 28, and apply the division lemma to get

306 = 28 x 10 + 26

We consider the new divisor 28 and the new remainder 26,and apply the division lemma to get

28 = 26 x 1 + 2

We consider the new divisor 26 and the new remainder 2,and apply the division lemma to get

26 = 2 x 13 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 640 and 334 is 2

Notice that 2 = HCF(26,2) = HCF(28,26) = HCF(306,28) = HCF(334,306) = HCF(640,334) .


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

Step 1: Since 156 > 2, we apply the division lemma to 156 and 2, to get

156 = 2 x 78 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 156 is 2

Notice that 2 = HCF(156,2) .
