HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 361, 587, 691 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 361, 587, 691 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, 587, 691 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, 587, 691 is 1.

HCF(361, 587, 691) = 1

Highest common factor (HCF) of 361, 587, 691 is 1.

Highest Common Factor of 361,587,691 using Euclid's algorithm

Highest Common Factor of 361,587,691 is 1

Step 1: Since 587 > 361, we apply the division lemma to 587 and 361, to get

587 = 361 x 1 + 226

Step 2: Since the reminder 361 ≠ 0, we apply division lemma to 226 and 361, to get

361 = 226 x 1 + 135

Step 3: We consider the new divisor 226 and the new remainder 135, and apply the division lemma to get

226 = 135 x 1 + 91

We consider the new divisor 135 and the new remainder 91,and apply the division lemma to get

135 = 91 x 1 + 44

We consider the new divisor 91 and the new remainder 44,and apply the division lemma to get

91 = 44 x 2 + 3

We consider the new divisor 44 and the new remainder 3,and apply the division lemma to get

44 = 3 x 14 + 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 361 and 587 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(44,3) = HCF(91,44) = HCF(135,91) = HCF(226,135) = HCF(361,226) = HCF(587,361) .

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

Step 1: Since 691 > 1, we apply the division lemma to 691 and 1, to get

691 = 1 x 691 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 691 is 1

Notice that 1 = HCF(691,1) .
