HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 616, 422, 225 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 616, 422, 225 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 616, 422, 225 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 616, 422, 225 is 1.

HCF(616, 422, 225) = 1

Highest Common Factor of 616,422,225 using Euclid's algorithm

Highest Common Factor of 616,422,225 is 1

Step 1: Since 616 > 422, we apply the division lemma to 616 and 422, to get

616 = 422 x 1 + 194

Step 2: Since the reminder 422 ≠ 0, we apply division lemma to 194 and 422, to get

422 = 194 x 2 + 34

Step 3: We consider the new divisor 194 and the new remainder 34, and apply the division lemma to get

194 = 34 x 5 + 24

We consider the new divisor 34 and the new remainder 24,and apply the division lemma to get

34 = 24 x 1 + 10

We consider the new divisor 24 and the new remainder 10,and apply the division lemma to get

24 = 10 x 2 + 4

We consider the new divisor 10 and the new remainder 4,and apply the division lemma to get

10 = 4 x 2 + 2

We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get

4 = 2 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 616 and 422 is 2

Notice that 2 = HCF(4,2) = HCF(10,4) = HCF(24,10) = HCF(34,24) = HCF(194,34) = HCF(422,194) = HCF(616,422) .

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

Step 1: Since 225 > 2, we apply the division lemma to 225 and 2, to get

225 = 2 x 112 + 1

Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 225 is 1

Notice that 1 = HCF(2,1) = HCF(225,2) .
