HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 487, 756 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 487, 756 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 487, 756 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 487, 756 is 1.

HCF(487, 756) = 1

Highest common factor (HCF) of 487, 756 is 1.

Highest Common Factor of 487,756 using Euclid's algorithm

Highest Common Factor of 487,756 is 1

Step 1: Since 756 > 487, we apply the division lemma to 756 and 487, to get

756 = 487 x 1 + 269

Step 2: Since the reminder 487 ≠ 0, we apply division lemma to 269 and 487, to get

487 = 269 x 1 + 218

Step 3: We consider the new divisor 269 and the new remainder 218, and apply the division lemma to get

269 = 218 x 1 + 51

We consider the new divisor 218 and the new remainder 51,and apply the division lemma to get

218 = 51 x 4 + 14

We consider the new divisor 51 and the new remainder 14,and apply the division lemma to get

51 = 14 x 3 + 9

We consider the new divisor 14 and the new remainder 9,and apply the division lemma to get

14 = 9 x 1 + 5

We consider the new divisor 9 and the new remainder 5,and apply the division lemma to get

9 = 5 x 1 + 4

We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get

5 = 4 x 1 + 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 487 and 756 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(9,5) = HCF(14,9) = HCF(51,14) = HCF(218,51) = HCF(269,218) = HCF(487,269) = HCF(756,487) .
