HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 300, 72 i.e. 12 the largest integer that leaves a remainder zero for all numbers.

HCF of 300, 72 is 12 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 300, 72 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 300, 72 is 12.

HCF(300, 72) = 12

HCF of 300, 72 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 300, 72 is 12.

Highest Common Factor of 300,72 using Euclid's algorithm

Highest Common Factor of 300,72 is 12

Step 1: Since 300 > 72, we apply the division lemma to 300 and 72, to get

300 = 72 x 4 + 12

Step 2: Since the reminder 72 ≠ 0, we apply division lemma to 12 and 72, to get

72 = 12 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 12, the HCF of 300 and 72 is 12

Notice that 12 = HCF(72,12) = HCF(300,72) .
