HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 688, 540 i.e. 4 the largest integer that leaves a remainder zero for all numbers.

HCF of 688, 540 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 688, 540 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 688, 540 is 4.

HCF(688, 540) = 4

Highest common factor (HCF) of 688, 540 is 4.

Highest Common Factor of 688,540 using Euclid's algorithm

Highest Common Factor of 688,540 is 4

Step 1: Since 688 > 540, we apply the division lemma to 688 and 540, to get

688 = 540 x 1 + 148

Step 2: Since the reminder 540 ≠ 0, we apply division lemma to 148 and 540, to get

540 = 148 x 3 + 96

Step 3: We consider the new divisor 148 and the new remainder 96, and apply the division lemma to get

148 = 96 x 1 + 52

We consider the new divisor 96 and the new remainder 52,and apply the division lemma to get

96 = 52 x 1 + 44

We consider the new divisor 52 and the new remainder 44,and apply the division lemma to get

52 = 44 x 1 + 8

We consider the new divisor 44 and the new remainder 8,and apply the division lemma to get

44 = 8 x 5 + 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 688 and 540 is 4

Notice that 4 = HCF(8,4) = HCF(44,8) = HCF(52,44) = HCF(96,52) = HCF(148,96) = HCF(540,148) = HCF(688,540) .
