HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 453, 254 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 453, 254 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 453, 254 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 453, 254 is 1.

HCF(453, 254) = 1

Highest common factor (HCF) of 453, 254 is 1.

Highest Common Factor of 453,254 using Euclid's algorithm

Highest Common Factor of 453,254 is 1

Step 1: Since 453 > 254, we apply the division lemma to 453 and 254, to get

453 = 254 x 1 + 199

Step 2: Since the reminder 254 ≠ 0, we apply division lemma to 199 and 254, to get

254 = 199 x 1 + 55

Step 3: We consider the new divisor 199 and the new remainder 55, and apply the division lemma to get

199 = 55 x 3 + 34

We consider the new divisor 55 and the new remainder 34,and apply the division lemma to get

55 = 34 x 1 + 21

We consider the new divisor 34 and the new remainder 21,and apply the division lemma to get

34 = 21 x 1 + 13

We consider the new divisor 21 and the new remainder 13,and apply the division lemma to get

21 = 13 x 1 + 8

We consider the new divisor 13 and the new remainder 8,and apply the division lemma to get

13 = 8 x 1 + 5

We consider the new divisor 8 and the new remainder 5,and apply the division lemma to get

8 = 5 x 1 + 3

We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get

5 = 3 x 1 + 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 453 and 254 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(13,8) = HCF(21,13) = HCF(34,21) = HCF(55,34) = HCF(199,55) = HCF(254,199) = HCF(453,254) .
