HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 628, 262, 481 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 628, 262, 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 628, 262, 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 628, 262, 481 is 1.

HCF(628, 262, 481) = 1

Highest common factor (HCF) of 628, 262, 481 is 1.

Highest Common Factor of 628,262,481 using Euclid's algorithm

Highest Common Factor of 628,262,481 is 1

Step 1: Since 628 > 262, we apply the division lemma to 628 and 262, to get

628 = 262 x 2 + 104

Step 2: Since the reminder 262 ≠ 0, we apply division lemma to 104 and 262, to get

262 = 104 x 2 + 54

Step 3: We consider the new divisor 104 and the new remainder 54, and apply the division lemma to get

104 = 54 x 1 + 50

We consider the new divisor 54 and the new remainder 50,and apply the division lemma to get

54 = 50 x 1 + 4

We consider the new divisor 50 and the new remainder 4,and apply the division lemma to get

50 = 4 x 12 + 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 628 and 262 is 2

Notice that 2 = HCF(4,2) = HCF(50,4) = HCF(54,50) = HCF(104,54) = HCF(262,104) = HCF(628,262) .

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) .
