HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 798, 453 i.e. 3 the largest integer that leaves a remainder zero for all numbers.

HCF of 798, 453 is 3 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 798, 453 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 798, 453 is 3.

HCF(798, 453) = 3

HCF of 798, 453 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 798, 453 is 3.

Highest Common Factor of 798,453 using Euclid's algorithm

Highest Common Factor of 798,453 is 3

Step 1: Since 798 > 453, we apply the division lemma to 798 and 453, to get

798 = 453 x 1 + 345

Step 2: Since the reminder 453 ≠ 0, we apply division lemma to 345 and 453, to get

453 = 345 x 1 + 108

Step 3: We consider the new divisor 345 and the new remainder 108, and apply the division lemma to get

345 = 108 x 3 + 21

We consider the new divisor 108 and the new remainder 21,and apply the division lemma to get

108 = 21 x 5 + 3

We consider the new divisor 21 and the new remainder 3,and apply the division lemma to get

21 = 3 x 7 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 798 and 453 is 3

Notice that 3 = HCF(21,3) = HCF(108,21) = HCF(345,108) = HCF(453,345) = HCF(798,453) .
