HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 361, 615, 551 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 361, 615, 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 361, 615, 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 361, 615, 551 is 1.

HCF(361, 615, 551) = 1

Highest common factor (HCF) of 361, 615, 551 is 1.

Highest Common Factor of 361,615,551 using Euclid's algorithm

Highest Common Factor of 361,615,551 is 1

Step 1: Since 615 > 361, we apply the division lemma to 615 and 361, to get

615 = 361 x 1 + 254

Step 2: Since the reminder 361 ≠ 0, we apply division lemma to 254 and 361, to get

361 = 254 x 1 + 107

Step 3: We consider the new divisor 254 and the new remainder 107, and apply the division lemma to get

254 = 107 x 2 + 40

We consider the new divisor 107 and the new remainder 40,and apply the division lemma to get

107 = 40 x 2 + 27

We consider the new divisor 40 and the new remainder 27,and apply the division lemma to get

40 = 27 x 1 + 13

We consider the new divisor 27 and the new remainder 13,and apply the division lemma to get

27 = 13 x 2 + 1

We consider the new divisor 13 and the new remainder 1,and apply the division lemma to get

13 = 1 x 13 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 361 and 615 is 1

Notice that 1 = HCF(13,1) = HCF(27,13) = HCF(40,27) = HCF(107,40) = HCF(254,107) = HCF(361,254) = HCF(615,361) .

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) .
