HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 485, 798, 551 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 485, 798, 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 485, 798, 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 485, 798, 551 is 1.

HCF(485, 798, 551) = 1

Highest common factor (HCF) of 485, 798, 551 is 1.

Highest Common Factor of 485,798,551 using Euclid's algorithm

Highest Common Factor of 485,798,551 is 1

Step 1: Since 798 > 485, we apply the division lemma to 798 and 485, to get

798 = 485 x 1 + 313

Step 2: Since the reminder 485 ≠ 0, we apply division lemma to 313 and 485, to get

485 = 313 x 1 + 172

Step 3: We consider the new divisor 313 and the new remainder 172, and apply the division lemma to get

313 = 172 x 1 + 141

We consider the new divisor 172 and the new remainder 141,and apply the division lemma to get

172 = 141 x 1 + 31

We consider the new divisor 141 and the new remainder 31,and apply the division lemma to get

141 = 31 x 4 + 17

We consider the new divisor 31 and the new remainder 17,and apply the division lemma to get

31 = 17 x 1 + 14

We consider the new divisor 17 and the new remainder 14,and apply the division lemma to get

17 = 14 x 1 + 3

We consider the new divisor 14 and the new remainder 3,and apply the division lemma to get

14 = 3 x 4 + 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 485 and 798 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(14,3) = HCF(17,14) = HCF(31,17) = HCF(141,31) = HCF(172,141) = HCF(313,172) = HCF(485,313) = HCF(798,485) .

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

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

551 = 1 x 551 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 551 is 1

Notice that 1 = HCF(551,1) .
