HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 551, 431, 494 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 551, 431, 494 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 551, 431, 494 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 551, 431, 494 is 1.

HCF(551, 431, 494) = 1

Highest common factor (HCF) of 551, 431, 494 is 1.

Highest Common Factor of 551,431,494 using Euclid's algorithm

Highest Common Factor of 551,431,494 is 1

Step 1: Since 551 > 431, we apply the division lemma to 551 and 431, to get

551 = 431 x 1 + 120

Step 2: Since the reminder 431 ≠ 0, we apply division lemma to 120 and 431, to get

431 = 120 x 3 + 71

Step 3: We consider the new divisor 120 and the new remainder 71, and apply the division lemma to get

120 = 71 x 1 + 49

We consider the new divisor 71 and the new remainder 49,and apply the division lemma to get

71 = 49 x 1 + 22

We consider the new divisor 49 and the new remainder 22,and apply the division lemma to get

49 = 22 x 2 + 5

We consider the new divisor 22 and the new remainder 5,and apply the division lemma to get

22 = 5 x 4 + 2

We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get

5 = 2 x 2 + 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 551 and 431 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(22,5) = HCF(49,22) = HCF(71,49) = HCF(120,71) = HCF(431,120) = HCF(551,431) .

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

Step 1: Since 494 > 1, we apply the division lemma to 494 and 1, to get

494 = 1 x 494 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 494 is 1

Notice that 1 = HCF(494,1) .
