HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 840, 910, 648 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 840, 910, 648 is 2 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 840, 910, 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 840, 910, 648 is 2.

HCF(840, 910, 648) = 2

HCF of 840, 910, 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 840, 910, 648 is 2.

Highest Common Factor of 840,910,648 using Euclid's algorithm

Highest Common Factor of 840,910,648 is 2

Step 1: Since 910 > 840, we apply the division lemma to 910 and 840, to get

910 = 840 x 1 + 70

Step 2: Since the reminder 840 ≠ 0, we apply division lemma to 70 and 840, to get

840 = 70 x 12 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 70, the HCF of 840 and 910 is 70

Notice that 70 = HCF(840,70) = HCF(910,840) .


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

Step 1: Since 648 > 70, we apply the division lemma to 648 and 70, to get

648 = 70 x 9 + 18

Step 2: Since the reminder 70 ≠ 0, we apply division lemma to 18 and 70, to get

70 = 18 x 3 + 16

Step 3: We consider the new divisor 18 and the new remainder 16, and apply the division lemma to get

18 = 16 x 1 + 2

We consider the new divisor 16 and the new remainder 2, and apply the division lemma to get

16 = 2 x 8 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 70 and 648 is 2

Notice that 2 = HCF(16,2) = HCF(18,16) = HCF(70,18) = HCF(648,70) .
