HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 446, 253 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 446, 253 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 446, 253 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 446, 253 is 1.

HCF(446, 253) = 1

Highest common factor (HCF) of 446, 253 is 1.

Highest Common Factor of 446,253 using Euclid's algorithm

Highest Common Factor of 446,253 is 1

Step 1: Since 446 > 253, we apply the division lemma to 446 and 253, to get

446 = 253 x 1 + 193

Step 2: Since the reminder 253 ≠ 0, we apply division lemma to 193 and 253, to get

253 = 193 x 1 + 60

Step 3: We consider the new divisor 193 and the new remainder 60, and apply the division lemma to get

193 = 60 x 3 + 13

We consider the new divisor 60 and the new remainder 13,and apply the division lemma to get

60 = 13 x 4 + 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 446 and 253 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(13,8) = HCF(60,13) = HCF(193,60) = HCF(253,193) = HCF(446,253) .
