HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 769, 451, 25 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 769, 451, 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 769, 451, 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 769, 451, 25 is 1.

HCF(769, 451, 25) = 1

Highest common factor (HCF) of 769, 451, 25 is 1.

Highest Common Factor of 769,451,25 using Euclid's algorithm

Highest Common Factor of 769,451,25 is 1

Step 1: Since 769 > 451, we apply the division lemma to 769 and 451, to get

769 = 451 x 1 + 318

Step 2: Since the reminder 451 ≠ 0, we apply division lemma to 318 and 451, to get

451 = 318 x 1 + 133

Step 3: We consider the new divisor 318 and the new remainder 133, and apply the division lemma to get

318 = 133 x 2 + 52

We consider the new divisor 133 and the new remainder 52,and apply the division lemma to get

133 = 52 x 2 + 29

We consider the new divisor 52 and the new remainder 29,and apply the division lemma to get

52 = 29 x 1 + 23

We consider the new divisor 29 and the new remainder 23,and apply the division lemma to get

29 = 23 x 1 + 6

We consider the new divisor 23 and the new remainder 6,and apply the division lemma to get

23 = 6 x 3 + 5

We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get

6 = 5 x 1 + 1

We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get

5 = 1 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 769 and 451 is 1

Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(23,6) = HCF(29,23) = HCF(52,29) = HCF(133,52) = HCF(318,133) = HCF(451,318) = HCF(769,451) .


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) .
