HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 648, 842, 488 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 648, 842, 488 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 648, 842, 488 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, 842, 488 is 2.

HCF(648, 842, 488) = 2

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 648, 842, 488 is 2.

Highest Common Factor of 648,842,488 using Euclid's algorithm

Highest Common Factor of 648,842,488 is 2

Step 1: Since 842 > 648, we apply the division lemma to 842 and 648, to get

842 = 648 x 1 + 194

Step 2: Since the reminder 648 ≠ 0, we apply division lemma to 194 and 648, to get

648 = 194 x 3 + 66

Step 3: We consider the new divisor 194 and the new remainder 66, and apply the division lemma to get

194 = 66 x 2 + 62

We consider the new divisor 66 and the new remainder 62,and apply the division lemma to get

66 = 62 x 1 + 4

We consider the new divisor 62 and the new remainder 4,and apply the division lemma to get

62 = 4 x 15 + 2

We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get

4 = 2 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 648 and 842 is 2

Notice that 2 = HCF(4,2) = HCF(62,4) = HCF(66,62) = HCF(194,66) = HCF(648,194) = HCF(842,648) .


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

Step 1: Since 488 > 2, we apply the division lemma to 488 and 2, to get

488 = 2 x 244 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 488 is 2

Notice that 2 = HCF(488,2) .
