HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 640, 270 i.e. 10 the largest integer that leaves a remainder zero for all numbers.

HCF of 640, 270 is 10 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, 270 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, 270 is 10.

HCF(640, 270) = 10

HCF of 640, 270 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, 270 is 10.

Highest Common Factor of 640,270 using Euclid's algorithm

Highest Common Factor of 640,270 is 10

Step 1: Since 640 > 270, we apply the division lemma to 640 and 270, to get

640 = 270 x 2 + 100

Step 2: Since the reminder 270 ≠ 0, we apply division lemma to 100 and 270, to get

270 = 100 x 2 + 70

Step 3: We consider the new divisor 100 and the new remainder 70, and apply the division lemma to get

100 = 70 x 1 + 30

We consider the new divisor 70 and the new remainder 30,and apply the division lemma to get

70 = 30 x 2 + 10

We consider the new divisor 30 and the new remainder 10,and apply the division lemma to get

30 = 10 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 10, the HCF of 640 and 270 is 10

Notice that 10 = HCF(30,10) = HCF(70,30) = HCF(100,70) = HCF(270,100) = HCF(640,270) .
