HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 627, 404, 974 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 627, 404, 974 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 627, 404, 974 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 627, 404, 974 is 1.

HCF(627, 404, 974) = 1

Highest common factor (HCF) of 627, 404, 974 is 1.

Highest Common Factor of 627,404,974 using Euclid's algorithm

Highest Common Factor of 627,404,974 is 1

Step 1: Since 627 > 404, we apply the division lemma to 627 and 404, to get

627 = 404 x 1 + 223

Step 2: Since the reminder 404 ≠ 0, we apply division lemma to 223 and 404, to get

404 = 223 x 1 + 181

Step 3: We consider the new divisor 223 and the new remainder 181, and apply the division lemma to get

223 = 181 x 1 + 42

We consider the new divisor 181 and the new remainder 42,and apply the division lemma to get

181 = 42 x 4 + 13

We consider the new divisor 42 and the new remainder 13,and apply the division lemma to get

42 = 13 x 3 + 3

We consider the new divisor 13 and the new remainder 3,and apply the division lemma to get

13 = 3 x 4 + 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 627 and 404 is 1

Notice that 1 = HCF(3,1) = HCF(13,3) = HCF(42,13) = HCF(181,42) = HCF(223,181) = HCF(404,223) = HCF(627,404) .

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

Step 1: Since 974 > 1, we apply the division lemma to 974 and 1, to get

974 = 1 x 974 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 974 is 1

Notice that 1 = HCF(974,1) .
