HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 495, 674, 982 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 495, 674, 982 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 495, 674, 982 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 495, 674, 982 is 1.

HCF(495, 674, 982) = 1

HCF of 495, 674, 982 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 495, 674, 982 is 1.

Highest Common Factor of 495,674,982 using Euclid's algorithm

Highest Common Factor of 495,674,982 is 1

Step 1: Since 674 > 495, we apply the division lemma to 674 and 495, to get

674 = 495 x 1 + 179

Step 2: Since the reminder 495 ≠ 0, we apply division lemma to 179 and 495, to get

495 = 179 x 2 + 137

Step 3: We consider the new divisor 179 and the new remainder 137, and apply the division lemma to get

179 = 137 x 1 + 42

We consider the new divisor 137 and the new remainder 42,and apply the division lemma to get

137 = 42 x 3 + 11

We consider the new divisor 42 and the new remainder 11,and apply the division lemma to get

42 = 11 x 3 + 9

We consider the new divisor 11 and the new remainder 9,and apply the division lemma to get

11 = 9 x 1 + 2

We consider the new divisor 9 and the new remainder 2,and apply the division lemma to get

9 = 2 x 4 + 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 495 and 674 is 1

Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(11,9) = HCF(42,11) = HCF(137,42) = HCF(179,137) = HCF(495,179) = HCF(674,495) .

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

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

982 = 1 x 982 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 982 is 1

Notice that 1 = HCF(982,1) .
