Given numbers are 792,372,872,420

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

The LCM of 792,372,872,420 is 93665880.

Find LCM of 792,372,872,420 with Prime Factorization

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

2 x 2 x 2 x 3 x 33 x 31 x 109 x 35 = 93665880

Therefore, the lowest common multiple of 792,372,872,420 is 93665880.

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.

792 x 372 x 872 x 420 = 107903093760

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.

792 : 1, 2, 3, 4, 6, 8, 9, 11, 12, 18, 22, 24, 33, 36, 44, 66, 72, 88, 99, 132, 198, 264, 396, 792

372 : 1, 2, 3, 4, 6, 12, 31, 62, 93, 124, 186, 372

872 : 1, 2, 4, 8, 109, 218, 436, 872

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 792,372,872,420, is 4.

Now, the common factors can be found like this.

792:2x 2x 2x 3x 3x 11

372:2x 2x 3x 31

872:2x 2x 2x 109

420:2x 2x 3x 5x 7

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 2x 2x 3x 3 = 288

Therefore, the value for common factors is 288.

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 = 107903093760/(4x288)

LCM = 107903093760/1152

LCM = 93665880

Thus, we can understand that the LCM of 792,372,872,420 is 93665880.
