HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 287, 474, 720 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 287, 474, 720 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 287, 474, 720 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 287, 474, 720 is 1.

HCF(287, 474, 720) = 1

Highest common factor (HCF) of 287, 474, 720 is 1.

Highest Common Factor of 287,474,720 using Euclid's algorithm

Highest Common Factor of 287,474,720 is 1

Step 1: Since 474 > 287, we apply the division lemma to 474 and 287, to get

474 = 287 x 1 + 187

Step 2: Since the reminder 287 ≠ 0, we apply division lemma to 187 and 287, to get

287 = 187 x 1 + 100

Step 3: We consider the new divisor 187 and the new remainder 100, and apply the division lemma to get

187 = 100 x 1 + 87

We consider the new divisor 100 and the new remainder 87,and apply the division lemma to get

100 = 87 x 1 + 13

We consider the new divisor 87 and the new remainder 13,and apply the division lemma to get

87 = 13 x 6 + 9

We consider the new divisor 13 and the new remainder 9,and apply the division lemma to get

13 = 9 x 1 + 4

We consider the new divisor 9 and the new remainder 4,and apply the division lemma to get

9 = 4 x 2 + 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 287 and 474 is 1

Notice that 1 = HCF(4,1) = HCF(9,4) = HCF(13,9) = HCF(87,13) = HCF(100,87) = HCF(187,100) = HCF(287,187) = HCF(474,287) .

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

Step 1: Since 720 > 1, we apply the division lemma to 720 and 1, to get

720 = 1 x 720 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 720 is 1

Notice that 1 = HCF(720,1) .
