HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 637, 383, 728 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 637, 383, 728 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 637, 383, 728 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 637, 383, 728 is 1.

HCF(637, 383, 728) = 1

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

HCF of:

Highest common factor (HCF) of 637, 383, 728 is 1.

Highest Common Factor of 637,383,728 using Euclid's algorithm

Highest Common Factor of 637,383,728 is 1

Step 1: Since 637 > 383, we apply the division lemma to 637 and 383, to get

637 = 383 x 1 + 254

Step 2: Since the reminder 383 ≠ 0, we apply division lemma to 254 and 383, to get

383 = 254 x 1 + 129

Step 3: We consider the new divisor 254 and the new remainder 129, and apply the division lemma to get

254 = 129 x 1 + 125

We consider the new divisor 129 and the new remainder 125,and apply the division lemma to get

129 = 125 x 1 + 4

We consider the new divisor 125 and the new remainder 4,and apply the division lemma to get

125 = 4 x 31 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 637 and 383 is 1

Notice that 1 = HCF(4,1) = HCF(125,4) = HCF(129,125) = HCF(254,129) = HCF(383,254) = HCF(637,383) .

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

Step 1: Since 728 > 1, we apply the division lemma to 728 and 1, to get

728 = 1 x 728 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 728 is 1

Notice that 1 = HCF(728,1) .
