HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 954, 551, 397 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 954, 551, 397 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 954, 551, 397 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 954, 551, 397 is 1.

HCF(954, 551, 397) = 1

Highest common factor (HCF) of 954, 551, 397 is 1.

Highest Common Factor of 954,551,397 using Euclid's algorithm

Highest Common Factor of 954,551,397 is 1

Step 1: Since 954 > 551, we apply the division lemma to 954 and 551, to get

954 = 551 x 1 + 403

Step 2: Since the reminder 551 ≠ 0, we apply division lemma to 403 and 551, to get

551 = 403 x 1 + 148

Step 3: We consider the new divisor 403 and the new remainder 148, and apply the division lemma to get

403 = 148 x 2 + 107

We consider the new divisor 148 and the new remainder 107,and apply the division lemma to get

148 = 107 x 1 + 41

We consider the new divisor 107 and the new remainder 41,and apply the division lemma to get

107 = 41 x 2 + 25

We consider the new divisor 41 and the new remainder 25,and apply the division lemma to get

41 = 25 x 1 + 16

We consider the new divisor 25 and the new remainder 16,and apply the division lemma to get

25 = 16 x 1 + 9

We consider the new divisor 16 and the new remainder 9,and apply the division lemma to get

16 = 9 x 1 + 7

We consider the new divisor 9 and the new remainder 7,and apply the division lemma to get

9 = 7 x 1 + 2

We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get

7 = 2 x 3 + 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 954 and 551 is 1

Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(9,7) = HCF(16,9) = HCF(25,16) = HCF(41,25) = HCF(107,41) = HCF(148,107) = HCF(403,148) = HCF(551,403) = HCF(954,551) .

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

Step 1: Since 397 > 1, we apply the division lemma to 397 and 1, to get

397 = 1 x 397 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 397 is 1

Notice that 1 = HCF(397,1) .
