HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 768, 270 i.e. 6 the largest integer that leaves a remainder zero for all numbers.

HCF of 768, 270 is 6 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 768, 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 768, 270 is 6.

HCF(768, 270) = 6

HCF of 768, 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 768, 270 is 6.

Highest Common Factor of 768,270 using Euclid's algorithm

Highest Common Factor of 768,270 is 6

Step 1: Since 768 > 270, we apply the division lemma to 768 and 270, to get

768 = 270 x 2 + 228

Step 2: Since the reminder 270 ≠ 0, we apply division lemma to 228 and 270, to get

270 = 228 x 1 + 42

Step 3: We consider the new divisor 228 and the new remainder 42, and apply the division lemma to get

228 = 42 x 5 + 18

We consider the new divisor 42 and the new remainder 18,and apply the division lemma to get

42 = 18 x 2 + 6

We consider the new divisor 18 and the new remainder 6,and apply the division lemma to get

18 = 6 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 768 and 270 is 6

Notice that 6 = HCF(18,6) = HCF(42,18) = HCF(228,42) = HCF(270,228) = HCF(768,270) .
