HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 665, 471, 54 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 665, 471, 54 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 665, 471, 54 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 665, 471, 54 is 1.

HCF(665, 471, 54) = 1

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

HCF of:

Highest common factor (HCF) of 665, 471, 54 is 1.

Highest Common Factor of 665,471,54 using Euclid's algorithm

Highest Common Factor of 665,471,54 is 1

Step 1: Since 665 > 471, we apply the division lemma to 665 and 471, to get

665 = 471 x 1 + 194

Step 2: Since the reminder 471 ≠ 0, we apply division lemma to 194 and 471, to get

471 = 194 x 2 + 83

Step 3: We consider the new divisor 194 and the new remainder 83, and apply the division lemma to get

194 = 83 x 2 + 28

We consider the new divisor 83 and the new remainder 28,and apply the division lemma to get

83 = 28 x 2 + 27

We consider the new divisor 28 and the new remainder 27,and apply the division lemma to get

28 = 27 x 1 + 1

We consider the new divisor 27 and the new remainder 1,and apply the division lemma to get

27 = 1 x 27 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 665 and 471 is 1

Notice that 1 = HCF(27,1) = HCF(28,27) = HCF(83,28) = HCF(194,83) = HCF(471,194) = HCF(665,471) .

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

Step 1: Since 54 > 1, we apply the division lemma to 54 and 1, to get

54 = 1 x 54 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 54 is 1

Notice that 1 = HCF(54,1) .
