HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 625, 384, 25 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 625, 384, 25 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 625, 384, 25 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 625, 384, 25 is 1.

HCF(625, 384, 25) = 1

Highest common factor (HCF) of 625, 384, 25 is 1.

Highest Common Factor of 625,384,25 using Euclid's algorithm

Highest Common Factor of 625,384,25 is 1

Step 1: Since 625 > 384, we apply the division lemma to 625 and 384, to get

625 = 384 x 1 + 241

Step 2: Since the reminder 384 ≠ 0, we apply division lemma to 241 and 384, to get

384 = 241 x 1 + 143

Step 3: We consider the new divisor 241 and the new remainder 143, and apply the division lemma to get

241 = 143 x 1 + 98

We consider the new divisor 143 and the new remainder 98,and apply the division lemma to get

143 = 98 x 1 + 45

We consider the new divisor 98 and the new remainder 45,and apply the division lemma to get

98 = 45 x 2 + 8

We consider the new divisor 45 and the new remainder 8,and apply the division lemma to get

45 = 8 x 5 + 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 625 and 384 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(45,8) = HCF(98,45) = HCF(143,98) = HCF(241,143) = HCF(384,241) = HCF(625,384) .

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

Step 1: Since 25 > 1, we apply the division lemma to 25 and 1, to get

25 = 1 x 25 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 25 is 1

Notice that 1 = HCF(25,1) .
