HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 980, 639, 652 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 980, 639, 652 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, 639, 652 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, 639, 652 is 1.

HCF(980, 639, 652) = 1

Highest common factor (HCF) of 980, 639, 652 is 1.

Highest Common Factor of 980,639,652 using Euclid's algorithm

Highest Common Factor of 980,639,652 is 1

Step 1: Since 980 > 639, we apply the division lemma to 980 and 639, to get

980 = 639 x 1 + 341

Step 2: Since the reminder 639 ≠ 0, we apply division lemma to 341 and 639, to get

639 = 341 x 1 + 298

Step 3: We consider the new divisor 341 and the new remainder 298, and apply the division lemma to get

341 = 298 x 1 + 43

We consider the new divisor 298 and the new remainder 43,and apply the division lemma to get

298 = 43 x 6 + 40

We consider the new divisor 43 and the new remainder 40,and apply the division lemma to get

43 = 40 x 1 + 3

We consider the new divisor 40 and the new remainder 3,and apply the division lemma to get

40 = 3 x 13 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 980 and 639 is 1

Notice that 1 = HCF(3,1) = HCF(40,3) = HCF(43,40) = HCF(298,43) = HCF(341,298) = HCF(639,341) = HCF(980,639) .

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

Step 1: Since 652 > 1, we apply the division lemma to 652 and 1, to get

652 = 1 x 652 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 652 is 1

Notice that 1 = HCF(652,1) .
