HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 979, 240, 401 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 979, 240, 401 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 979, 240, 401 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 979, 240, 401 is 1.

HCF(979, 240, 401) = 1

Highest common factor (HCF) of 979, 240, 401 is 1.

Highest Common Factor of 979,240,401 using Euclid's algorithm

Highest Common Factor of 979,240,401 is 1

Step 1: Since 979 > 240, we apply the division lemma to 979 and 240, to get

979 = 240 x 4 + 19

Step 2: Since the reminder 240 ≠ 0, we apply division lemma to 19 and 240, to get

240 = 19 x 12 + 12

Step 3: We consider the new divisor 19 and the new remainder 12, and apply the division lemma to get

19 = 12 x 1 + 7

We consider the new divisor 12 and the new remainder 7,and apply the division lemma to get

12 = 7 x 1 + 5

We consider the new divisor 7 and the new remainder 5,and apply the division lemma to get

7 = 5 x 1 + 2

We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get

5 = 2 x 2 + 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 979 and 240 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(12,7) = HCF(19,12) = HCF(240,19) = HCF(979,240) .

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

Step 1: Since 401 > 1, we apply the division lemma to 401 and 1, to get

401 = 1 x 401 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 401 is 1

Notice that 1 = HCF(401,1) .
