HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 577, 491, 577 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 577, 491, 577 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 577, 491, 577 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 577, 491, 577 is 1.

HCF(577, 491, 577) = 1

Highest common factor (HCF) of 577, 491, 577 is 1.

Highest Common Factor of 577,491,577 using Euclid's algorithm

Highest Common Factor of 577,491,577 is 1

Step 1: Since 577 > 491, we apply the division lemma to 577 and 491, to get

577 = 491 x 1 + 86

Step 2: Since the reminder 491 ≠ 0, we apply division lemma to 86 and 491, to get

491 = 86 x 5 + 61

Step 3: We consider the new divisor 86 and the new remainder 61, and apply the division lemma to get

86 = 61 x 1 + 25

We consider the new divisor 61 and the new remainder 25,and apply the division lemma to get

61 = 25 x 2 + 11

We consider the new divisor 25 and the new remainder 11,and apply the division lemma to get

25 = 11 x 2 + 3

We consider the new divisor 11 and the new remainder 3,and apply the division lemma to get

11 = 3 x 3 + 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 577 and 491 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(11,3) = HCF(25,11) = HCF(61,25) = HCF(86,61) = HCF(491,86) = HCF(577,491) .

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

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

577 = 1 x 577 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 577 is 1

Notice that 1 = HCF(577,1) .
