Given numbers are 744,139,728,247,220

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

The LCM of 744,139,728,247,220 is 9834344520.

Find LCM of 744,139,728,247,220 with Prime Factorization

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

2 x 2 x 2 x 13 x 93 x 139 x 7 x 19 x 55 = 9834344520

Therefore, the lowest common multiple of 744,139,728,247,220 is 9834344520.

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.

744 x 139 x 728 x 247 x 220 = 4091087320320

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.

744 : 1, 2, 3, 4, 6, 8, 12, 24, 31, 62, 93, 124, 186, 248, 372, 744

139 : 1, 139

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

247 : 1, 13, 19, 247

220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 744,139,728,247,220, is 1.

Now, the common factors can be found like this.

744:2x 2x 2x 3x 31

139:139

728:2x 2x 2x 7x 13

247:13x 19

220:2x 2x 5x 11

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 2x 2x 2x 13 = 416

Therefore, the value for common factors is 416.

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 = 4091087320320/(1x416)

LCM = 4091087320320/416

LCM = 9834344520

Thus, we can understand that the LCM of 744,139,728,247,220 is 9834344520.
