HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 20, 64, 34, 712 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 20, 64, 34, 712 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 20, 64, 34, 712 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 20, 64, 34, 712 is 2.

HCF(20, 64, 34, 712) = 2

HCF of 20, 64, 34, 712 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 20, 64, 34, 712 is 2.

Highest Common Factor of 20,64,34,712 using Euclid's algorithm

Highest Common Factor of 20,64,34,712 is 2

Step 1: Since 64 > 20, we apply the division lemma to 64 and 20, to get

64 = 20 x 3 + 4

Step 2: Since the reminder 20 ≠ 0, we apply division lemma to 4 and 20, to get

20 = 4 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 20 and 64 is 4

Notice that 4 = HCF(20,4) = HCF(64,20) .


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

Step 1: Since 34 > 4, we apply the division lemma to 34 and 4, to get

34 = 4 x 8 + 2

Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 2 and 4, to get

4 = 2 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 4 and 34 is 2

Notice that 2 = HCF(4,2) = HCF(34,4) .


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

Step 1: Since 712 > 2, we apply the division lemma to 712 and 2, to get

712 = 2 x 356 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 712 is 2

Notice that 2 = HCF(712,2) .
