Given numbers are 642,803,654,423

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

The LCM of 642,803,654,423 is 7923119094.

Find LCM of 642,803,654,423 with Prime Factorization

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

2 x 3 x 107 x 803 x 109 x 141 = 7923119094

Therefore, the lowest common multiple of 642,803,654,423 is 7923119094.

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 803 x 654 x 423 = 142616143692

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

803 : 1, 11, 73, 803

654 : 1, 2, 3, 6, 109, 218, 327, 654

423 : 1, 3, 9, 47, 141, 423

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,803,654,423, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

803:11x 73

654:2x 3x 109

423:3x 3x 47

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

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 142616143692/(1x18)

LCM = 142616143692/18

LCM = 7923119094

Thus, we can understand that the LCM of 642,803,654,423 is 7923119094.
