HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 365, 168, 855 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 365, 168, 855 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 365, 168, 855 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 365, 168, 855 is 1.

HCF(365, 168, 855) = 1

Highest common factor (HCF) of 365, 168, 855 is 1.

Highest Common Factor of 365,168,855 using Euclid's algorithm

Highest Common Factor of 365,168,855 is 1

Step 1: Since 365 > 168, we apply the division lemma to 365 and 168, to get

365 = 168 x 2 + 29

Step 2: Since the reminder 168 ≠ 0, we apply division lemma to 29 and 168, to get

168 = 29 x 5 + 23

Step 3: We consider the new divisor 29 and the new remainder 23, and apply the division lemma to get

29 = 23 x 1 + 6

We consider the new divisor 23 and the new remainder 6,and apply the division lemma to get

23 = 6 x 3 + 5

We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get

6 = 5 x 1 + 1

We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get

5 = 1 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 365 and 168 is 1

Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(23,6) = HCF(29,23) = HCF(168,29) = HCF(365,168) .

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

Step 1: Since 855 > 1, we apply the division lemma to 855 and 1, to get

855 = 1 x 855 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 855 is 1

Notice that 1 = HCF(855,1) .
