HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 546, 855, 979 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 546, 855, 979 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 546, 855, 979 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 546, 855, 979 is 1.

HCF(546, 855, 979) = 1

Highest common factor (HCF) of 546, 855, 979 is 1.

Highest Common Factor of 546,855,979 using Euclid's algorithm

Highest Common Factor of 546,855,979 is 1

Step 1: Since 855 > 546, we apply the division lemma to 855 and 546, to get

855 = 546 x 1 + 309

Step 2: Since the reminder 546 ≠ 0, we apply division lemma to 309 and 546, to get

546 = 309 x 1 + 237

Step 3: We consider the new divisor 309 and the new remainder 237, and apply the division lemma to get

309 = 237 x 1 + 72

We consider the new divisor 237 and the new remainder 72,and apply the division lemma to get

237 = 72 x 3 + 21

We consider the new divisor 72 and the new remainder 21,and apply the division lemma to get

72 = 21 x 3 + 9

We consider the new divisor 21 and the new remainder 9,and apply the division lemma to get

21 = 9 x 2 + 3

We consider the new divisor 9 and the new remainder 3,and apply the division lemma to get

9 = 3 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 546 and 855 is 3

Notice that 3 = HCF(9,3) = HCF(21,9) = HCF(72,21) = HCF(237,72) = HCF(309,237) = HCF(546,309) = HCF(855,546) .

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

Step 1: Since 979 > 3, we apply the division lemma to 979 and 3, to get

979 = 3 x 326 + 1

Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, 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 3 and 979 is 1

Notice that 1 = HCF(3,1) = HCF(979,3) .
