HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 386, 969, 225 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 386, 969, 225 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 386, 969, 225 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 386, 969, 225 is 1.

HCF(386, 969, 225) = 1

Highest common factor (HCF) of 386, 969, 225 is 1.

Highest Common Factor of 386,969,225 using Euclid's algorithm

Highest Common Factor of 386,969,225 is 1

Step 1: Since 969 > 386, we apply the division lemma to 969 and 386, to get

969 = 386 x 2 + 197

Step 2: Since the reminder 386 ≠ 0, we apply division lemma to 197 and 386, to get

386 = 197 x 1 + 189

Step 3: We consider the new divisor 197 and the new remainder 189, and apply the division lemma to get

197 = 189 x 1 + 8

We consider the new divisor 189 and the new remainder 8,and apply the division lemma to get

189 = 8 x 23 + 5

We consider the new divisor 8 and the new remainder 5,and apply the division lemma to get

8 = 5 x 1 + 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 386 and 969 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(189,8) = HCF(197,189) = HCF(386,197) = HCF(969,386) .

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

Step 1: Since 225 > 1, we apply the division lemma to 225 and 1, to get

225 = 1 x 225 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 225 is 1

Notice that 1 = HCF(225,1) .
