HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 456, 996, 648 i.e. 12 the largest integer that leaves a remainder zero for all numbers.

HCF of 456, 996, 648 is 12 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 456, 996, 648 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 456, 996, 648 is 12.

HCF(456, 996, 648) = 12

HCF of 456, 996, 648 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 456, 996, 648 is 12.

Highest Common Factor of 456,996,648 using Euclid's algorithm

Highest Common Factor of 456,996,648 is 12

Step 1: Since 996 > 456, we apply the division lemma to 996 and 456, to get

996 = 456 x 2 + 84

Step 2: Since the reminder 456 ≠ 0, we apply division lemma to 84 and 456, to get

456 = 84 x 5 + 36

Step 3: We consider the new divisor 84 and the new remainder 36, and apply the division lemma to get

84 = 36 x 2 + 12

We consider the new divisor 36 and the new remainder 12, and apply the division lemma to get

36 = 12 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 12, the HCF of 456 and 996 is 12

Notice that 12 = HCF(36,12) = HCF(84,36) = HCF(456,84) = HCF(996,456) .


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

Step 1: Since 648 > 12, we apply the division lemma to 648 and 12, to get

648 = 12 x 54 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 12, the HCF of 12 and 648 is 12

Notice that 12 = HCF(648,12) .
