HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 12, 253, 497 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 12, 253, 497 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 12, 253, 497 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 12, 253, 497 is 1.

HCF(12, 253, 497) = 1

HCF of 12, 253, 497 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 12, 253, 497 is 1.

Highest Common Factor of 12,253,497 using Euclid's algorithm

Highest Common Factor of 12,253,497 is 1

Step 1: Since 253 > 12, we apply the division lemma to 253 and 12, to get

253 = 12 x 21 + 1

Step 2: Since the reminder 12 ≠ 0, we apply division lemma to 1 and 12, to get

12 = 1 x 12 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 12 and 253 is 1

Notice that 1 = HCF(12,1) = HCF(253,12) .


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

Step 1: Since 497 > 1, we apply the division lemma to 497 and 1, to get

497 = 1 x 497 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 497 is 1

Notice that 1 = HCF(497,1) .
