HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 720, 144, 72 i.e. 72 the largest integer that leaves a remainder zero for all numbers.

HCF of 720, 144, 72 is 72 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 720, 144, 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 720, 144, 72 is 72.

HCF(720, 144, 72) = 72

HCF of 720, 144, 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 720, 144, 72 is 72.

Highest Common Factor of 720,144,72 using Euclid's algorithm

Highest Common Factor of 720,144,72 is 72

Step 1: Since 720 > 144, we apply the division lemma to 720 and 144, to get

720 = 144 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 144, the HCF of 720 and 144 is 144

Notice that 144 = HCF(720,144) .


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

Step 1: Since 144 > 72, we apply the division lemma to 144 and 72, to get

144 = 72 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 72, the HCF of 144 and 72 is 72

Notice that 72 = HCF(144,72) .
