HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 30, 272 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 30, 272 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 30, 272 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 30, 272 is 2.

HCF(30, 272) = 2

HCF of 30, 272 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 30, 272 is 2.

Highest Common Factor of 30,272 using Euclid's algorithm

Highest Common Factor of 30,272 is 2

Step 1: Since 272 > 30, we apply the division lemma to 272 and 30, to get

272 = 30 x 9 + 2

Step 2: Since the reminder 30 ≠ 0, we apply division lemma to 2 and 30, to get

30 = 2 x 15 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 30 and 272 is 2

Notice that 2 = HCF(30,2) = HCF(272,30) .
