HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 80, 60 i.e. 20 the largest integer that leaves a remainder zero for all numbers.

HCF of 80, 60 is 20 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 80, 60 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 80, 60 is 20.

HCF(80, 60) = 20

HCF of 80, 60 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 80, 60 is 20.

Highest Common Factor of 80,60 using Euclid's algorithm

Highest Common Factor of 80,60 is 20

Step 1: Since 80 > 60, we apply the division lemma to 80 and 60, to get

80 = 60 x 1 + 20

Step 2: Since the reminder 60 ≠ 0, we apply division lemma to 20 and 60, to get

60 = 20 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 20, the HCF of 80 and 60 is 20

Notice that 20 = HCF(60,20) = HCF(80,60) .
