HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 330, 721, 488 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 330, 721, 488 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 330, 721, 488 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 330, 721, 488 is 1.

HCF(330, 721, 488) = 1

Highest common factor (HCF) of 330, 721, 488 is 1.

Highest Common Factor of 330,721,488 using Euclid's algorithm

Highest Common Factor of 330,721,488 is 1

Step 1: Since 721 > 330, we apply the division lemma to 721 and 330, to get

721 = 330 x 2 + 61

Step 2: Since the reminder 330 ≠ 0, we apply division lemma to 61 and 330, to get

330 = 61 x 5 + 25

Step 3: 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 330 and 721 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(11,3) = HCF(25,11) = HCF(61,25) = HCF(330,61) = HCF(721,330) .

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

Step 1: Since 488 > 1, we apply the division lemma to 488 and 1, to get

488 = 1 x 488 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 488 is 1

Notice that 1 = HCF(488,1) .
