HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 648, 96918 i.e. 6 the largest integer that leaves a remainder zero for all numbers.

HCF of 648, 96918 is 6 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 648, 96918 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 648, 96918 is 6.

HCF(648, 96918) = 6

Highest common factor (HCF) of 648, 96918 is 6.

Highest Common Factor of 648,96918 using Euclid's algorithm

Highest Common Factor of 648,96918 is 6

Step 1: Since 96918 > 648, we apply the division lemma to 96918 and 648, to get

96918 = 648 x 149 + 366

Step 2: Since the reminder 648 ≠ 0, we apply division lemma to 366 and 648, to get

648 = 366 x 1 + 282

Step 3: We consider the new divisor 366 and the new remainder 282, and apply the division lemma to get

366 = 282 x 1 + 84

We consider the new divisor 282 and the new remainder 84,and apply the division lemma to get

282 = 84 x 3 + 30

We consider the new divisor 84 and the new remainder 30,and apply the division lemma to get

84 = 30 x 2 + 24

We consider the new divisor 30 and the new remainder 24,and apply the division lemma to get

30 = 24 x 1 + 6

We consider the new divisor 24 and the new remainder 6,and apply the division lemma to get

24 = 6 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 648 and 96918 is 6

Notice that 6 = HCF(24,6) = HCF(30,24) = HCF(84,30) = HCF(282,84) = HCF(366,282) = HCF(648,366) = HCF(96918,648) .
