HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 791, 577, 659 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 791, 577, 659 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 791, 577, 659 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 791, 577, 659 is 1.

HCF(791, 577, 659) = 1

HCF of 791, 577, 659 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 791, 577, 659 is 1.

Highest Common Factor of 791,577,659 using Euclid's algorithm

Highest Common Factor of 791,577,659 is 1

Step 1: Since 791 > 577, we apply the division lemma to 791 and 577, to get

791 = 577 x 1 + 214

Step 2: Since the reminder 577 ≠ 0, we apply division lemma to 214 and 577, to get

577 = 214 x 2 + 149

Step 3: We consider the new divisor 214 and the new remainder 149, and apply the division lemma to get

214 = 149 x 1 + 65

We consider the new divisor 149 and the new remainder 65,and apply the division lemma to get

149 = 65 x 2 + 19

We consider the new divisor 65 and the new remainder 19,and apply the division lemma to get

65 = 19 x 3 + 8

We consider the new divisor 19 and the new remainder 8,and apply the division lemma to get

19 = 8 x 2 + 3

We consider the new divisor 8 and the new remainder 3,and apply the division lemma to get

8 = 3 x 2 + 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 791 and 577 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(8,3) = HCF(19,8) = HCF(65,19) = HCF(149,65) = HCF(214,149) = HCF(577,214) = HCF(791,577) .

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

Step 1: Since 659 > 1, we apply the division lemma to 659 and 1, to get

659 = 1 x 659 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 659 is 1

Notice that 1 = HCF(659,1) .
