Given numbers are 642,902,107,496

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

The LCM of 642,902,107,496 is 71806416.

Find LCM of 642,902,107,496 with Prime Factorization

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

2 x 107 x 3 x 451 x 1 x 248 = 71806416

Therefore, the lowest common multiple of 642,902,107,496 is 71806416.

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.

642 x 902 x 107 x 496 = 30733146048

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.

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

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

107 : 1, 107

496 : 1, 2, 4, 8, 16, 31, 62, 124, 248, 496

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,902,107,496, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

902:2x 11x 41

107:107

496:2x 2x 2x 2x 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 107 = 428

Therefore, the value for common factors is 428.

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 = 30733146048/(1x428)

LCM = 30733146048/428

LCM = 71806416

Thus, we can understand that the LCM of 642,902,107,496 is 71806416.
