HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 747, 872, 473 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 747, 872, 473 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 747, 872, 473 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 747, 872, 473 is 1.

HCF(747, 872, 473) = 1

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

HCF of:

Highest common factor (HCF) of 747, 872, 473 is 1.

Highest Common Factor of 747,872,473 using Euclid's algorithm

Highest Common Factor of 747,872,473 is 1

Step 1: Since 872 > 747, we apply the division lemma to 872 and 747, to get

872 = 747 x 1 + 125

Step 2: Since the reminder 747 ≠ 0, we apply division lemma to 125 and 747, to get

747 = 125 x 5 + 122

Step 3: We consider the new divisor 125 and the new remainder 122, and apply the division lemma to get

125 = 122 x 1 + 3

We consider the new divisor 122 and the new remainder 3,and apply the division lemma to get

122 = 3 x 40 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma 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 747 and 872 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(122,3) = HCF(125,122) = HCF(747,125) = HCF(872,747) .

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

Step 1: Since 473 > 1, we apply the division lemma to 473 and 1, to get

473 = 1 x 473 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 473 is 1

Notice that 1 = HCF(473,1) .
