Given numbers are 721,273,130,642,648

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

The LCM of 721,273,130,642,648 is 3249431640.

Find LCM of 721,273,130,642,648 with Prime Factorization

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

2 x 3 x 7 x 13 x 103 x 1 x 5 x 107 x 108 = 3249431640

Therefore, the lowest common multiple of 721,273,130,642,648 is 3249431640.

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.

721 x 273 x 130 x 642 x 648 = 10645138052640

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.

721 : 1, 7, 103, 721

273 : 1, 3, 7, 13, 21, 39, 91, 273

130 : 1, 2, 5, 10, 13, 26, 65, 130

642 : 1, 2, 3, 6, 107, 214, 321, 642

648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,273,130,642,648, is 1.

Now, the common factors can be found like this.

721:7x 103

273:3x 7x 13

130:2x 5x 13

642:2x 3x 107

648:2x 2x 2x 3x 3x 3x 3

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

2x 2x 3x 3x 7x 13 = 3276

Therefore, the value for common factors is 3276.

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 = 10645138052640/(1x3276)

LCM = 10645138052640/3276

LCM = 3249431640

Thus, we can understand that the LCM of 721,273,130,642,648 is 3249431640.
