HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 912, 769, 251 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 912, 769, 251 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 912, 769, 251 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 912, 769, 251 is 1.

HCF(912, 769, 251) = 1

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 912, 769, 251 is 1.

Highest Common Factor of 912,769,251 using Euclid's algorithm

Highest Common Factor of 912,769,251 is 1

Step 1: Since 912 > 769, we apply the division lemma to 912 and 769, to get

912 = 769 x 1 + 143

Step 2: Since the reminder 769 ≠ 0, we apply division lemma to 143 and 769, to get

769 = 143 x 5 + 54

Step 3: We consider the new divisor 143 and the new remainder 54, and apply the division lemma to get

143 = 54 x 2 + 35

We consider the new divisor 54 and the new remainder 35,and apply the division lemma to get

54 = 35 x 1 + 19

We consider the new divisor 35 and the new remainder 19,and apply the division lemma to get

35 = 19 x 1 + 16

We consider the new divisor 19 and the new remainder 16,and apply the division lemma to get

19 = 16 x 1 + 3

We consider the new divisor 16 and the new remainder 3,and apply the division lemma to get

16 = 3 x 5 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 912 and 769 is 1

Notice that 1 = HCF(3,1) = HCF(16,3) = HCF(19,16) = HCF(35,19) = HCF(54,35) = HCF(143,54) = HCF(769,143) = HCF(912,769) .

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

Step 1: Since 251 > 1, we apply the division lemma to 251 and 1, to get

251 = 1 x 251 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 251 is 1

Notice that 1 = HCF(251,1) .
