HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 253, 287 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 253, 287 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 253, 287 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 253, 287 is 1.

HCF(253, 287) = 1

HCF of 253, 287 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 253, 287 is 1.

Highest Common Factor of 253,287 using Euclid's algorithm

Highest Common Factor of 253,287 is 1

Step 1: Since 287 > 253, we apply the division lemma to 287 and 253, to get

287 = 253 x 1 + 34

Step 2: Since the reminder 253 ≠ 0, we apply division lemma to 34 and 253, to get

253 = 34 x 7 + 15

Step 3: We consider the new divisor 34 and the new remainder 15, and apply the division lemma to get

34 = 15 x 2 + 4

We consider the new divisor 15 and the new remainder 4,and apply the division lemma to get

15 = 4 x 3 + 3

We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get

4 = 3 x 1 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 253 and 287 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(15,4) = HCF(34,15) = HCF(253,34) = HCF(287,253) .
