HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 754, 420, 481 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 754, 420, 481 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 754, 420, 481 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 754, 420, 481 is 1.

HCF(754, 420, 481) = 1

Highest common factor (HCF) of 754, 420, 481 is 1.

Highest Common Factor of 754,420,481 using Euclid's algorithm

Highest Common Factor of 754,420,481 is 1

Step 1: Since 754 > 420, we apply the division lemma to 754 and 420, to get

754 = 420 x 1 + 334

Step 2: Since the reminder 420 ≠ 0, we apply division lemma to 334 and 420, to get

420 = 334 x 1 + 86

Step 3: We consider the new divisor 334 and the new remainder 86, and apply the division lemma to get

334 = 86 x 3 + 76

We consider the new divisor 86 and the new remainder 76,and apply the division lemma to get

86 = 76 x 1 + 10

We consider the new divisor 76 and the new remainder 10,and apply the division lemma to get

76 = 10 x 7 + 6

We consider the new divisor 10 and the new remainder 6,and apply the division lemma to get

10 = 6 x 1 + 4

We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get

6 = 4 x 1 + 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 754 and 420 is 2

Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(10,6) = HCF(76,10) = HCF(86,76) = HCF(334,86) = HCF(420,334) = HCF(754,420) .


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

Step 1: Since 481 > 2, we apply the division lemma to 481 and 2, to get

481 = 2 x 240 + 1

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

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 2 and 481 is 1

Notice that 1 = HCF(2,1) = HCF(481,2) .
