HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 325, 421, 916 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 325, 421, 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 325, 421, 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 325, 421, 916 is 1.

HCF(325, 421, 916) = 1

HCF of 325, 421, 916 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

Highest common factor (HCF) of 325, 421, 916 is 1.

Highest Common Factor of 325,421,916 using Euclid's algorithm

Highest Common Factor of 325,421,916 is 1

Step 1: Since 421 > 325, we apply the division lemma to 421 and 325, to get

421 = 325 x 1 + 96

Step 2: Since the reminder 325 ≠ 0, we apply division lemma to 96 and 325, to get

325 = 96 x 3 + 37

Step 3: We consider the new divisor 96 and the new remainder 37, and apply the division lemma to get

96 = 37 x 2 + 22

We consider the new divisor 37 and the new remainder 22,and apply the division lemma to get

37 = 22 x 1 + 15

We consider the new divisor 22 and the new remainder 15,and apply the division lemma to get

22 = 15 x 1 + 7

We consider the new divisor 15 and the new remainder 7,and apply the division lemma to get

15 = 7 x 2 + 1

We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get

7 = 1 x 7 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 325 and 421 is 1

Notice that 1 = HCF(7,1) = HCF(15,7) = HCF(22,15) = HCF(37,22) = HCF(96,37) = HCF(325,96) = HCF(421,325) .

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) .
