HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 99, 764, 903 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 99, 764, 903 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 99, 764, 903 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 99, 764, 903 is 1.

HCF(99, 764, 903) = 1

HCF of 99, 764, 903 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 99, 764, 903 is 1.

Highest Common Factor of 99,764,903 using Euclid's algorithm

Highest Common Factor of 99,764,903 is 1

Step 1: Since 764 > 99, we apply the division lemma to 764 and 99, to get

764 = 99 x 7 + 71

Step 2: Since the reminder 99 ≠ 0, we apply division lemma to 71 and 99, to get

99 = 71 x 1 + 28

Step 3: We consider the new divisor 71 and the new remainder 28, and apply the division lemma to get

71 = 28 x 2 + 15

We consider the new divisor 28 and the new remainder 15,and apply the division lemma to get

28 = 15 x 1 + 13

We consider the new divisor 15 and the new remainder 13,and apply the division lemma to get

15 = 13 x 1 + 2

We consider the new divisor 13 and the new remainder 2,and apply the division lemma to get

13 = 2 x 6 + 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 99 and 764 is 1

Notice that 1 = HCF(2,1) = HCF(13,2) = HCF(15,13) = HCF(28,15) = HCF(71,28) = HCF(99,71) = HCF(764,99) .

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

Step 1: Since 903 > 1, we apply the division lemma to 903 and 1, to get

903 = 1 x 903 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 903 is 1

Notice that 1 = HCF(903,1) .
