Given numbers are 130,407,902,78

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

The LCM of 130,407,902,78 is 6507930.

Find LCM of 130,407,902,78 with Prime Factorization

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

2 x 11 x 13 x 5 x 37 x 41 x 3 = 6507930

Therefore, the lowest common multiple of 130,407,902,78 is 6507930.

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.

130 x 407 x 902 x 78 = 3722535960

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.

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

407 : 1, 11, 37, 407

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

78 : 1, 2, 3, 6, 13, 26, 39, 78

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 130,407,902,78, is 1.

Now, the common factors can be found like this.

130:2x 5x 13

407:11x 37

902:2x 11x 41

78:2x 3x 13

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 11x 13 = 572

Therefore, the value for common factors is 572.

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 = 3722535960/(1x572)

LCM = 3722535960/572

LCM = 6507930

Thus, we can understand that the LCM of 130,407,902,78 is 6507930.
