HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 982, 634, 700, 172 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 982, 634, 700, 172 is 2 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 982, 634, 700, 172 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 982, 634, 700, 172 is 2.

HCF(982, 634, 700, 172) = 2

Highest Common Factor of 982,634,700,172 using Euclid's algorithm

Highest Common Factor of 982,634,700,172 is 2

Step 1: Since 982 > 634, we apply the division lemma to 982 and 634, to get

982 = 634 x 1 + 348

Step 2: Since the reminder 634 ≠ 0, we apply division lemma to 348 and 634, to get

634 = 348 x 1 + 286

Step 3: We consider the new divisor 348 and the new remainder 286, and apply the division lemma to get

348 = 286 x 1 + 62

We consider the new divisor 286 and the new remainder 62,and apply the division lemma to get

286 = 62 x 4 + 38

We consider the new divisor 62 and the new remainder 38,and apply the division lemma to get

62 = 38 x 1 + 24

We consider the new divisor 38 and the new remainder 24,and apply the division lemma to get

38 = 24 x 1 + 14

We consider the new divisor 24 and the new remainder 14,and apply the division lemma to get

24 = 14 x 1 + 10

We consider the new divisor 14 and the new remainder 10,and apply the division lemma to get

14 = 10 x 1 + 4

We consider the new divisor 10 and the new remainder 4,and apply the division lemma to get

10 = 4 x 2 + 2

We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get

4 = 2 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 982 and 634 is 2

Notice that 2 = HCF(4,2) = HCF(10,4) = HCF(14,10) = HCF(24,14) = HCF(38,24) = HCF(62,38) = HCF(286,62) = HCF(348,286) = HCF(634,348) = HCF(982,634) .

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

Step 1: Since 700 > 2, we apply the division lemma to 700 and 2, to get

700 = 2 x 350 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 700 is 2

Notice that 2 = HCF(700,2) .

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

Step 1: Since 172 > 2, we apply the division lemma to 172 and 2, to get

172 = 2 x 86 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 172 is 2

Notice that 2 = HCF(172,2) .
