HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 232, 781, 225 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 232, 781, 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 232, 781, 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 232, 781, 225 is 1.

HCF(232, 781, 225) = 1

Highest common factor (HCF) of 232, 781, 225 is 1.

Highest Common Factor of 232,781,225 using Euclid's algorithm

Highest Common Factor of 232,781,225 is 1

Step 1: Since 781 > 232, we apply the division lemma to 781 and 232, to get

781 = 232 x 3 + 85

Step 2: Since the reminder 232 ≠ 0, we apply division lemma to 85 and 232, to get

232 = 85 x 2 + 62

Step 3: We consider the new divisor 85 and the new remainder 62, and apply the division lemma to get

85 = 62 x 1 + 23

We consider the new divisor 62 and the new remainder 23,and apply the division lemma to get

62 = 23 x 2 + 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 232 and 781 is 1

Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(16,7) = HCF(23,16) = HCF(62,23) = HCF(85,62) = HCF(232,85) = HCF(781,232) .

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) .
