HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 207, 572, 728 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 207, 572, 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 207, 572, 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 207, 572, 728 is 1.

HCF(207, 572, 728) = 1

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

HCF of:

Highest common factor (HCF) of 207, 572, 728 is 1.

Highest Common Factor of 207,572,728 using Euclid's algorithm

Highest Common Factor of 207,572,728 is 1

Step 1: Since 572 > 207, we apply the division lemma to 572 and 207, to get

572 = 207 x 2 + 158

Step 2: Since the reminder 207 ≠ 0, we apply division lemma to 158 and 207, to get

207 = 158 x 1 + 49

Step 3: We consider the new divisor 158 and the new remainder 49, and apply the division lemma to get

158 = 49 x 3 + 11

We consider the new divisor 49 and the new remainder 11,and apply the division lemma to get

49 = 11 x 4 + 5

We consider the new divisor 11 and the new remainder 5,and apply the division lemma to get

11 = 5 x 2 + 1

We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get

5 = 1 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 207 and 572 is 1

Notice that 1 = HCF(5,1) = HCF(11,5) = HCF(49,11) = HCF(158,49) = HCF(207,158) = HCF(572,207) .

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) .
