Given numbers are 642,237,922,755

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

The LCM of 642,237,922,755 is 17652653490.

Find LCM of 642,237,922,755 with Prime Factorization

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

2 x 3 x 107 x 79 x 461 x 755 = 17652653490

Therefore, the lowest common multiple of 642,237,922,755 is 17652653490.

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 237 x 922 x 755 = 105915920940

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

237 : 1, 3, 79, 237

922 : 1, 2, 461, 922

755 : 1, 5, 151, 755

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,237,922,755, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

237:3x 79

922:2x 461

755:5x 151

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 105915920940/(1x6)

LCM = 105915920940/6

LCM = 17652653490

Thus, we can understand that the LCM of 642,237,922,755 is 17652653490.
