HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 993, 764, 57 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 993, 764, 57 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 993, 764, 57 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 993, 764, 57 is 1.

HCF(993, 764, 57) = 1

Highest common factor (HCF) of 993, 764, 57 is 1.

Highest Common Factor of 993,764,57 using Euclid's algorithm

Highest Common Factor of 993,764,57 is 1

Step 1: Since 993 > 764, we apply the division lemma to 993 and 764, to get

993 = 764 x 1 + 229

Step 2: Since the reminder 764 ≠ 0, we apply division lemma to 229 and 764, to get

764 = 229 x 3 + 77

Step 3: We consider the new divisor 229 and the new remainder 77, and apply the division lemma to get

229 = 77 x 2 + 75

We consider the new divisor 77 and the new remainder 75,and apply the division lemma to get

77 = 75 x 1 + 2

We consider the new divisor 75 and the new remainder 2,and apply the division lemma to get

75 = 2 x 37 + 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 993 and 764 is 1

Notice that 1 = HCF(2,1) = HCF(75,2) = HCF(77,75) = HCF(229,77) = HCF(764,229) = HCF(993,764) .

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

Step 1: Since 57 > 1, we apply the division lemma to 57 and 1, to get

57 = 1 x 57 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 57 is 1

Notice that 1 = HCF(57,1) .
