HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 837, 688 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 837, 688 is 1 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 837, 688 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 837, 688 is 1.

HCF(837, 688) = 1

Highest common factor (HCF) of 837, 688 is 1.

Highest Common Factor of 837,688 using Euclid's algorithm

Highest Common Factor of 837,688 is 1

Step 1: Since 837 > 688, we apply the division lemma to 837 and 688, to get

837 = 688 x 1 + 149

Step 2: Since the reminder 688 ≠ 0, we apply division lemma to 149 and 688, to get

688 = 149 x 4 + 92

Step 3: We consider the new divisor 149 and the new remainder 92, and apply the division lemma to get

149 = 92 x 1 + 57

We consider the new divisor 92 and the new remainder 57,and apply the division lemma to get

92 = 57 x 1 + 35

We consider the new divisor 57 and the new remainder 35,and apply the division lemma to get

57 = 35 x 1 + 22

We consider the new divisor 35 and the new remainder 22,and apply the division lemma to get

35 = 22 x 1 + 13

We consider the new divisor 22 and the new remainder 13,and apply the division lemma to get

22 = 13 x 1 + 9

We consider the new divisor 13 and the new remainder 9,and apply the division lemma to get

13 = 9 x 1 + 4

We consider the new divisor 9 and the new remainder 4,and apply the division lemma to get

9 = 4 x 2 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 837 and 688 is 1

Notice that 1 = HCF(4,1) = HCF(9,4) = HCF(13,9) = HCF(22,13) = HCF(35,22) = HCF(57,35) = HCF(92,57) = HCF(149,92) = HCF(688,149) = HCF(837,688) .
