HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 561, 979, 367 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 561, 979, 367 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 561, 979, 367 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 561, 979, 367 is 1.

HCF(561, 979, 367) = 1

HCF of 561, 979, 367 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 561, 979, 367 is 1.

Highest Common Factor of 561,979,367 using Euclid's algorithm

Highest Common Factor of 561,979,367 is 1

Step 1: Since 979 > 561, we apply the division lemma to 979 and 561, to get

979 = 561 x 1 + 418

Step 2: Since the reminder 561 ≠ 0, we apply division lemma to 418 and 561, to get

561 = 418 x 1 + 143

Step 3: We consider the new divisor 418 and the new remainder 143, and apply the division lemma to get

418 = 143 x 2 + 132

We consider the new divisor 143 and the new remainder 132,and apply the division lemma to get

143 = 132 x 1 + 11

We consider the new divisor 132 and the new remainder 11,and apply the division lemma to get

132 = 11 x 12 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 11, the HCF of 561 and 979 is 11

Notice that 11 = HCF(132,11) = HCF(143,132) = HCF(418,143) = HCF(561,418) = HCF(979,561) .


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

Step 1: Since 367 > 11, we apply the division lemma to 367 and 11, to get

367 = 11 x 33 + 4

Step 2: Since the reminder 11 ≠ 0, we apply division lemma to 4 and 11, to get

11 = 4 x 2 + 3

Step 3: We consider the new divisor 4 and the new remainder 3, and apply the division lemma to get

4 = 3 x 1 + 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 11 and 367 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(11,4) = HCF(367,11) .
