HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 648, 168 i.e. 24 the largest integer that leaves a remainder zero for all numbers.

HCF of 648, 168 is 24 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, 168 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, 168 is 24.

HCF(648, 168) = 24

Highest common factor (HCF) of 648, 168 is 24.

Highest Common Factor of 648,168 using Euclid's algorithm

Highest Common Factor of 648,168 is 24

Step 1: Since 648 > 168, we apply the division lemma to 648 and 168, to get

648 = 168 x 3 + 144

Step 2: Since the reminder 168 ≠ 0, we apply division lemma to 144 and 168, to get

168 = 144 x 1 + 24

Step 3: We consider the new divisor 144 and the new remainder 24, and apply the division lemma to get

144 = 24 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 24, the HCF of 648 and 168 is 24

Notice that 24 = HCF(144,24) = HCF(168,144) = HCF(648,168) .
