HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 857, 365 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 857, 365 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 857, 365 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 857, 365 is 1.

HCF(857, 365) = 1

Highest common factor (HCF) of 857, 365 is 1.

Highest Common Factor of 857,365 using Euclid's algorithm

Highest Common Factor of 857,365 is 1

Step 1: Since 857 > 365, we apply the division lemma to 857 and 365, to get

857 = 365 x 2 + 127

Step 2: Since the reminder 365 ≠ 0, we apply division lemma to 127 and 365, to get

365 = 127 x 2 + 111

Step 3: We consider the new divisor 127 and the new remainder 111, and apply the division lemma to get

127 = 111 x 1 + 16

We consider the new divisor 111 and the new remainder 16,and apply the division lemma to get

111 = 16 x 6 + 15

We consider the new divisor 16 and the new remainder 15,and apply the division lemma to get

16 = 15 x 1 + 1

We consider the new divisor 15 and the new remainder 1,and apply the division lemma to get

15 = 1 x 15 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 857 and 365 is 1

Notice that 1 = HCF(15,1) = HCF(16,15) = HCF(111,16) = HCF(127,111) = HCF(365,127) = HCF(857,365) .
