HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 747, 473, 488 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 747, 473, 488 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, 473, 488 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, 473, 488 is 1.

HCF(747, 473, 488) = 1

Highest common factor (HCF) of 747, 473, 488 is 1.

Highest Common Factor of 747,473,488 using Euclid's algorithm

Highest Common Factor of 747,473,488 is 1

Step 1: Since 747 > 473, we apply the division lemma to 747 and 473, to get

747 = 473 x 1 + 274

Step 2: Since the reminder 473 ≠ 0, we apply division lemma to 274 and 473, to get

473 = 274 x 1 + 199

Step 3: We consider the new divisor 274 and the new remainder 199, and apply the division lemma to get

274 = 199 x 1 + 75

We consider the new divisor 199 and the new remainder 75,and apply the division lemma to get

199 = 75 x 2 + 49

We consider the new divisor 75 and the new remainder 49,and apply the division lemma to get

75 = 49 x 1 + 26

We consider the new divisor 49 and the new remainder 26,and apply the division lemma to get

49 = 26 x 1 + 23

We consider the new divisor 26 and the new remainder 23,and apply the division lemma to get

26 = 23 x 1 + 3

We consider the new divisor 23 and the new remainder 3,and apply the division lemma to get

23 = 3 x 7 + 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 473 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(23,3) = HCF(26,23) = HCF(49,26) = HCF(75,49) = HCF(199,75) = HCF(274,199) = HCF(473,274) = HCF(747,473) .

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

Step 1: Since 488 > 1, we apply the division lemma to 488 and 1, to get

488 = 1 x 488 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 488 is 1

Notice that 1 = HCF(488,1) .
