HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 388, 225 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 388, 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 388, 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 388, 225 is 1.

HCF(388, 225) = 1

Highest common factor (HCF) of 388, 225 is 1.

Highest Common Factor of 388,225 using Euclid's algorithm

Highest Common Factor of 388,225 is 1

Step 1: Since 388 > 225, we apply the division lemma to 388 and 225, to get

388 = 225 x 1 + 163

Step 2: Since the reminder 225 ≠ 0, we apply division lemma to 163 and 225, to get

225 = 163 x 1 + 62

Step 3: We consider the new divisor 163 and the new remainder 62, and apply the division lemma to get

163 = 62 x 2 + 39

We consider the new divisor 62 and the new remainder 39,and apply the division lemma to get

62 = 39 x 1 + 23

We consider the new divisor 39 and the new remainder 23,and apply the division lemma to get

39 = 23 x 1 + 16

We consider the new divisor 23 and the new remainder 16,and apply the division lemma to get

23 = 16 x 1 + 7

We consider the new divisor 16 and the new remainder 7,and apply the division lemma to get

16 = 7 x 2 + 2

We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get

7 = 2 x 3 + 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 388 and 225 is 1

Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(16,7) = HCF(23,16) = HCF(39,23) = HCF(62,39) = HCF(163,62) = HCF(225,163) = HCF(388,225) .
