HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 428, 251, 966 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 428, 251, 966 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 428, 251, 966 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 428, 251, 966 is 1.

HCF(428, 251, 966) = 1

HCF of 428, 251, 966 using Euclid's algorithm

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

HCF of:

Highest common factor (HCF) of 428, 251, 966 is 1.

Highest Common Factor of 428,251,966 using Euclid's algorithm

Highest Common Factor of 428,251,966 is 1

Step 1: Since 428 > 251, we apply the division lemma to 428 and 251, to get

428 = 251 x 1 + 177

Step 2: Since the reminder 251 ≠ 0, we apply division lemma to 177 and 251, to get

251 = 177 x 1 + 74

Step 3: We consider the new divisor 177 and the new remainder 74, and apply the division lemma to get

177 = 74 x 2 + 29

We consider the new divisor 74 and the new remainder 29,and apply the division lemma to get

74 = 29 x 2 + 16

We consider the new divisor 29 and the new remainder 16,and apply the division lemma to get

29 = 16 x 1 + 13

We consider the new divisor 16 and the new remainder 13,and apply the division lemma to get

16 = 13 x 1 + 3

We consider the new divisor 13 and the new remainder 3,and apply the division lemma to get

13 = 3 x 4 + 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 428 and 251 is 1

Notice that 1 = HCF(3,1) = HCF(13,3) = HCF(16,13) = HCF(29,16) = HCF(74,29) = HCF(177,74) = HCF(251,177) = HCF(428,251) .

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

Step 1: Since 966 > 1, we apply the division lemma to 966 and 1, to get

966 = 1 x 966 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 966 is 1

Notice that 1 = HCF(966,1) .
