HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 816, 325 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 816, 325 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 816, 325 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 816, 325 is 1.

HCF(816, 325) = 1

Highest common factor (HCF) of 816, 325 is 1.

Highest Common Factor of 816,325 using Euclid's algorithm

Highest Common Factor of 816,325 is 1

Step 1: Since 816 > 325, we apply the division lemma to 816 and 325, to get

816 = 325 x 2 + 166

Step 2: Since the reminder 325 ≠ 0, we apply division lemma to 166 and 325, to get

325 = 166 x 1 + 159

Step 3: We consider the new divisor 166 and the new remainder 159, and apply the division lemma to get

166 = 159 x 1 + 7

We consider the new divisor 159 and the new remainder 7,and apply the division lemma to get

159 = 7 x 22 + 5

We consider the new divisor 7 and the new remainder 5,and apply the division lemma to get

7 = 5 x 1 + 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 816 and 325 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(159,7) = HCF(166,159) = HCF(325,166) = HCF(816,325) .
