HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 361, 864 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 361, 864 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, 864 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, 864 is 1.

HCF(361, 864) = 1

Highest common factor (HCF) of 361, 864 is 1.

Highest Common Factor of 361,864 using Euclid's algorithm

Highest Common Factor of 361,864 is 1

Step 1: Since 864 > 361, we apply the division lemma to 864 and 361, to get

864 = 361 x 2 + 142

Step 2: Since the reminder 361 ≠ 0, we apply division lemma to 142 and 361, to get

361 = 142 x 2 + 77

Step 3: We consider the new divisor 142 and the new remainder 77, and apply the division lemma to get

142 = 77 x 1 + 65

We consider the new divisor 77 and the new remainder 65,and apply the division lemma to get

77 = 65 x 1 + 12

We consider the new divisor 65 and the new remainder 12,and apply the division lemma to get

65 = 12 x 5 + 5

We consider the new divisor 12 and the new remainder 5,and apply the division lemma to get

12 = 5 x 2 + 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 361 and 864 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(12,5) = HCF(65,12) = HCF(77,65) = HCF(142,77) = HCF(361,142) = HCF(864,361) .
