Given numbers are 153,638,778,398,930

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

The LCM of 153,638,778,398,930 is 1171241589870.

Find LCM of 153,638,778,398,930 with Prime Factorization

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

2 x 3 x 51 x 319 x 389 x 199 x 155 = 1171241589870

Therefore, the lowest common multiple of 153,638,778,398,930 is 1171241589870.

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.

153 x 638 x 778 x 398 x 930 = 28109798156880

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.

153 : 1, 3, 9, 17, 51, 153

638 : 1, 2, 11, 22, 29, 58, 319, 638

778 : 1, 2, 389, 778

398 : 1, 2, 199, 398

930 : 1, 2, 3, 5, 6, 10, 15, 30, 31, 62, 93, 155, 186, 310, 465, 930

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 153,638,778,398,930, is 1.

Now, the common factors can be found like this.

153:3x 3x 17

638:2x 11x 29

778:2x 389

398:2x 199

930:2x 3x 5x 31

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 3 = 24

Therefore, the value for common factors is 24.

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 = 28109798156880/(1x24)

LCM = 28109798156880/24

LCM = 1171241589870

Thus, we can understand that the LCM of 153,638,778,398,930 is 1171241589870.
