HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 25, 561, 916 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 25, 561, 916 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 25, 561, 916 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 25, 561, 916 is 1.

HCF(25, 561, 916) = 1

HCF of 25, 561, 916 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 25, 561, 916 is 1.

Highest Common Factor of 25,561,916 using Euclid's algorithm

Highest Common Factor of 25,561,916 is 1

Step 1: Since 561 > 25, we apply the division lemma to 561 and 25, to get

561 = 25 x 22 + 11

Step 2: Since the reminder 25 ≠ 0, we apply division lemma to 11 and 25, to get

25 = 11 x 2 + 3

Step 3: We consider the new divisor 11 and the new remainder 3, and apply the division lemma to get

11 = 3 x 3 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 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 25 and 561 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(11,3) = HCF(25,11) = HCF(561,25) .


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

Step 1: Since 916 > 1, we apply the division lemma to 916 and 1, to get

916 = 1 x 916 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 916 is 1

Notice that 1 = HCF(916,1) .
