HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 980, 851, 531 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 980, 851, 531 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 980, 851, 531 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 980, 851, 531 is 1.

HCF(980, 851, 531) = 1

HCF of 980, 851, 531 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 980, 851, 531 is 1.

Highest Common Factor of 980,851,531 using Euclid's algorithm

Highest Common Factor of 980,851,531 is 1

Step 1: Since 980 > 851, we apply the division lemma to 980 and 851, to get

980 = 851 x 1 + 129

Step 2: Since the reminder 851 ≠ 0, we apply division lemma to 129 and 851, to get

851 = 129 x 6 + 77

Step 3: We consider the new divisor 129 and the new remainder 77, and apply the division lemma to get

129 = 77 x 1 + 52

We consider the new divisor 77 and the new remainder 52,and apply the division lemma to get

77 = 52 x 1 + 25

We consider the new divisor 52 and the new remainder 25,and apply the division lemma to get

52 = 25 x 2 + 2

We consider the new divisor 25 and the new remainder 2,and apply the division lemma to get

25 = 2 x 12 + 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 980 and 851 is 1

Notice that 1 = HCF(2,1) = HCF(25,2) = HCF(52,25) = HCF(77,52) = HCF(129,77) = HCF(851,129) = HCF(980,851) .

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

Step 1: Since 531 > 1, we apply the division lemma to 531 and 1, to get

531 = 1 x 531 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 531 is 1

Notice that 1 = HCF(531,1) .
