HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 620, 744, 481 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 620, 744, 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 620, 744, 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 620, 744, 481 is 1.

HCF(620, 744, 481) = 1

Highest common factor (HCF) of 620, 744, 481 is 1.

Highest Common Factor of 620,744,481 using Euclid's algorithm

Highest Common Factor of 620,744,481 is 1

Step 1: Since 744 > 620, we apply the division lemma to 744 and 620, to get

744 = 620 x 1 + 124

Step 2: Since the reminder 620 ≠ 0, we apply division lemma to 124 and 620, to get

620 = 124 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 124, the HCF of 620 and 744 is 124

Notice that 124 = HCF(620,124) = HCF(744,620) .

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

Step 1: Since 481 > 124, we apply the division lemma to 481 and 124, to get

481 = 124 x 3 + 109

Step 2: Since the reminder 124 ≠ 0, we apply division lemma to 109 and 124, to get

124 = 109 x 1 + 15

Step 3: We consider the new divisor 109 and the new remainder 15, and apply the division lemma to get

109 = 15 x 7 + 4

We consider the new divisor 15 and the new remainder 4,and apply the division lemma to get

15 = 4 x 3 + 3

We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get

4 = 3 x 1 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma 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 124 and 481 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(15,4) = HCF(109,15) = HCF(124,109) = HCF(481,124) .
