HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 471, 648, 64 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 471, 648, 64 is 1 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 471, 648, 64 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 471, 648, 64 is 1.

HCF(471, 648, 64) = 1

Highest common factor (HCF) of 471, 648, 64 is 1.

Highest Common Factor of 471,648,64 using Euclid's algorithm

Highest Common Factor of 471,648,64 is 1

Step 1: Since 648 > 471, we apply the division lemma to 648 and 471, to get

648 = 471 x 1 + 177

Step 2: Since the reminder 471 ≠ 0, we apply division lemma to 177 and 471, to get

471 = 177 x 2 + 117

Step 3: We consider the new divisor 177 and the new remainder 117, and apply the division lemma to get

177 = 117 x 1 + 60

We consider the new divisor 117 and the new remainder 60,and apply the division lemma to get

117 = 60 x 1 + 57

We consider the new divisor 60 and the new remainder 57,and apply the division lemma to get

60 = 57 x 1 + 3

We consider the new divisor 57 and the new remainder 3,and apply the division lemma to get

57 = 3 x 19 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 471 and 648 is 3

Notice that 3 = HCF(57,3) = HCF(60,57) = HCF(117,60) = HCF(177,117) = HCF(471,177) = HCF(648,471) .


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

Step 1: Since 64 > 3, we apply the division lemma to 64 and 3, to get

64 = 3 x 21 + 1

Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 64 is 1

Notice that 1 = HCF(3,1) = HCF(64,3) .
