HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 724, 84 i.e. 4 the largest integer that leaves a remainder zero for all numbers.

HCF of 724, 84 is 4 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 724, 84 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 724, 84 is 4.

HCF(724, 84) = 4

Highest common factor (HCF) of 724, 84 is 4.

Highest Common Factor of 724,84 using Euclid's algorithm

Highest Common Factor of 724,84 is 4

Step 1: Since 724 > 84, we apply the division lemma to 724 and 84, to get

724 = 84 x 8 + 52

Step 2: Since the reminder 84 ≠ 0, we apply division lemma to 52 and 84, to get

84 = 52 x 1 + 32

Step 3: We consider the new divisor 52 and the new remainder 32, and apply the division lemma to get

52 = 32 x 1 + 20

We consider the new divisor 32 and the new remainder 20,and apply the division lemma to get

32 = 20 x 1 + 12

We consider the new divisor 20 and the new remainder 12,and apply the division lemma to get

20 = 12 x 1 + 8

We consider the new divisor 12 and the new remainder 8,and apply the division lemma to get

12 = 8 x 1 + 4

We consider the new divisor 8 and the new remainder 4,and apply the division lemma to get

8 = 4 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 724 and 84 is 4

Notice that 4 = HCF(8,4) = HCF(12,8) = HCF(20,12) = HCF(32,20) = HCF(52,32) = HCF(84,52) = HCF(724,84) .
