HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 986, 753, 428 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 986, 753, 428 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 986, 753, 428 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 986, 753, 428 is 1.

HCF(986, 753, 428) = 1

Highest common factor (HCF) of 986, 753, 428 is 1.

Highest Common Factor of 986,753,428 using Euclid's algorithm

Highest Common Factor of 986,753,428 is 1

Step 1: Since 986 > 753, we apply the division lemma to 986 and 753, to get

986 = 753 x 1 + 233

Step 2: Since the reminder 753 ≠ 0, we apply division lemma to 233 and 753, to get

753 = 233 x 3 + 54

Step 3: We consider the new divisor 233 and the new remainder 54, and apply the division lemma to get

233 = 54 x 4 + 17

We consider the new divisor 54 and the new remainder 17,and apply the division lemma to get

54 = 17 x 3 + 3

We consider the new divisor 17 and the new remainder 3,and apply the division lemma to get

17 = 3 x 5 + 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 986 and 753 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(17,3) = HCF(54,17) = HCF(233,54) = HCF(753,233) = HCF(986,753) .

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

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

428 = 1 x 428 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 428 is 1

Notice that 1 = HCF(428,1) .
