HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 365, 256 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 365, 256 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, 256 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, 256 is 1.

HCF(365, 256) = 1

Highest common factor (HCF) of 365, 256 is 1.

Highest Common Factor of 365,256 using Euclid's algorithm

Highest Common Factor of 365,256 is 1

Step 1: Since 365 > 256, we apply the division lemma to 365 and 256, to get

365 = 256 x 1 + 109

Step 2: Since the reminder 256 ≠ 0, we apply division lemma to 109 and 256, to get

256 = 109 x 2 + 38

Step 3: We consider the new divisor 109 and the new remainder 38, and apply the division lemma to get

109 = 38 x 2 + 33

We consider the new divisor 38 and the new remainder 33,and apply the division lemma to get

38 = 33 x 1 + 5

We consider the new divisor 33 and the new remainder 5,and apply the division lemma to get

33 = 5 x 6 + 3

We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get

5 = 3 x 1 + 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 365 and 256 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(33,5) = HCF(38,33) = HCF(109,38) = HCF(256,109) = HCF(365,256) .
