Given numbers are 7171,2020

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 7171,2020 is 143420.

Find LCM of 7171,2020 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

101 x 71 x 20 = 143420

Therefore, the lowest common multiple of 7171,2020 is 143420.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

7171 x 2020 = 14485420

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

7171 : 1, 71, 101, 7171

2020 : 1, 2, 4, 5, 10, 20, 101, 202, 404, 505, 1010, 2020

101 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 7171,2020, is 101.

Now, the common factors can be found like this.

7171:71x 101

2020:2x 2x 5x 101

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

= 1

Therefore, the value for common factors is 1.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 14485420/(101x1)

LCM = 14485420/101

LCM = 143420

Thus, we can understand that the LCM of 7171,2020 is 143420.
