HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 681, 497, 156 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 681, 497, 156 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 681, 497, 156 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 681, 497, 156 is 1.

HCF(681, 497, 156) = 1

HCF of 681, 497, 156 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 681, 497, 156 is 1.

Highest Common Factor of 681,497,156 using Euclid's algorithm

Highest Common Factor of 681,497,156 is 1

Step 1: Since 681 > 497, we apply the division lemma to 681 and 497, to get

681 = 497 x 1 + 184

Step 2: Since the reminder 497 ≠ 0, we apply division lemma to 184 and 497, to get

497 = 184 x 2 + 129

Step 3: We consider the new divisor 184 and the new remainder 129, and apply the division lemma to get

184 = 129 x 1 + 55

We consider the new divisor 129 and the new remainder 55,and apply the division lemma to get

129 = 55 x 2 + 19

We consider the new divisor 55 and the new remainder 19,and apply the division lemma to get

55 = 19 x 2 + 17

We consider the new divisor 19 and the new remainder 17,and apply the division lemma to get

19 = 17 x 1 + 2

We consider the new divisor 17 and the new remainder 2,and apply the division lemma to get

17 = 2 x 8 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 681 and 497 is 1

Notice that 1 = HCF(2,1) = HCF(17,2) = HCF(19,17) = HCF(55,19) = HCF(129,55) = HCF(184,129) = HCF(497,184) = HCF(681,497) .

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

Step 1: Since 156 > 1, we apply the division lemma to 156 and 1, to get

156 = 1 x 156 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 156 is 1

Notice that 1 = HCF(156,1) .
