Given numbers are 778,902,718,980,408

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

The LCM of 778,902,718,980,408 is 6295740795960.

Find LCM of 778,902,718,980,408 with Prime Factorization

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

2 x 2 x 389 x 451 x 359 x 245 x 102 = 6295740795960

Therefore, the lowest common multiple of 778,902,718,980,408 is 6295740795960.

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.

778 x 902 x 718 x 980 x 408 = 201463705470720

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.

778 : 1, 2, 389, 778

902 : 1, 2, 11, 22, 41, 82, 451, 902

718 : 1, 2, 359, 718

980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980

408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 778,902,718,980,408, is 2.

Now, the common factors can be found like this.

778:2x 389

902:2x 11x 41

718:2x 359

980:2x 2x 5x 7x 7

408:2x 2x 2x 3x 17

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 2 = 16

Therefore, the value for common factors is 16.

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 = 201463705470720/(2x16)

LCM = 201463705470720/32

LCM = 6295740795960

Thus, we can understand that the LCM of 778,902,718,980,408 is 6295740795960.
