HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 982, 775, 657 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 982, 775, 657 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 982, 775, 657 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, 775, 657 is 1.

HCF(982, 775, 657) = 1

HCF of 982, 775, 657 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 982, 775, 657 is 1.

Highest Common Factor of 982,775,657 using Euclid's algorithm

Highest Common Factor of 982,775,657 is 1

Step 1: Since 982 > 775, we apply the division lemma to 982 and 775, to get

982 = 775 x 1 + 207

Step 2: Since the reminder 775 ≠ 0, we apply division lemma to 207 and 775, to get

775 = 207 x 3 + 154

Step 3: We consider the new divisor 207 and the new remainder 154, and apply the division lemma to get

207 = 154 x 1 + 53

We consider the new divisor 154 and the new remainder 53,and apply the division lemma to get

154 = 53 x 2 + 48

We consider the new divisor 53 and the new remainder 48,and apply the division lemma to get

53 = 48 x 1 + 5

We consider the new divisor 48 and the new remainder 5,and apply the division lemma to get

48 = 5 x 9 + 3

We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get

5 = 3 x 1 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 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 982 and 775 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(48,5) = HCF(53,48) = HCF(154,53) = HCF(207,154) = HCF(775,207) = HCF(982,775) .

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

Step 1: Since 657 > 1, we apply the division lemma to 657 and 1, to get

657 = 1 x 657 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 657 is 1

Notice that 1 = HCF(657,1) .
