Given numbers are 720,342,453,579,979

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

The LCM of 720,342,453,579,979 is 390304038960.

Find LCM of 720,342,453,579,979 with Prime Factorization

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

2 x 3 x 3 x 40 x 19 x 151 x 193 x 979 = 390304038960

Therefore, the lowest common multiple of 720,342,453,579,979 is 390304038960.

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.

720 x 342 x 453 x 579 x 979 = 63229254311520

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.

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342

453 : 1, 3, 151, 453

579 : 1, 3, 193, 579

979 : 1, 11, 89, 979

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 720,342,453,579,979, is 1.

Now, the common factors can be found like this.

720:2x 2x 2x 2x 3x 3x 5

342:2x 3x 3x 19

453:3x 151

579:3x 193

979:11x 89

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

2x 3x 3x 3x 3 = 162

Therefore, the value for common factors is 162.

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 = 63229254311520/(1x162)

LCM = 63229254311520/162

LCM = 390304038960

Thus, we can understand that the LCM of 720,342,453,579,979 is 390304038960.
