HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 486, 718, 551 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 486, 718, 551 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 486, 718, 551 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 486, 718, 551 is 1.

HCF(486, 718, 551) = 1

Highest common factor (HCF) of 486, 718, 551 is 1.

Highest Common Factor of 486,718,551 using Euclid's algorithm

Highest Common Factor of 486,718,551 is 1

Step 1: Since 718 > 486, we apply the division lemma to 718 and 486, to get

718 = 486 x 1 + 232

Step 2: Since the reminder 486 ≠ 0, we apply division lemma to 232 and 486, to get

486 = 232 x 2 + 22

Step 3: We consider the new divisor 232 and the new remainder 22, and apply the division lemma to get

232 = 22 x 10 + 12

We consider the new divisor 22 and the new remainder 12,and apply the division lemma to get

22 = 12 x 1 + 10

We consider the new divisor 12 and the new remainder 10,and apply the division lemma to get

12 = 10 x 1 + 2

We consider the new divisor 10 and the new remainder 2,and apply the division lemma to get

10 = 2 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 486 and 718 is 2

Notice that 2 = HCF(10,2) = HCF(12,10) = HCF(22,12) = HCF(232,22) = HCF(486,232) = HCF(718,486) .

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

Step 1: Since 551 > 2, we apply the division lemma to 551 and 2, to get

551 = 2 x 275 + 1

Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 551 is 1

Notice that 1 = HCF(2,1) = HCF(551,2) .
