Given numbers are 642,273,594,146,715

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

The LCM of 642,273,594,146,715 is 2111078970.

Find LCM of 642,273,594,146,715 with Prime Factorization

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

2 x 3 x 11 x 13 x 107 x 7 x 9 x 73 x 5 = 2111078970

Therefore, the lowest common multiple of 642,273,594,146,715 is 2111078970.

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 273 x 594 x 146 x 715 = 10867834537560

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

273 : 1, 3, 7, 13, 21, 39, 91, 273

594 : 1, 2, 3, 6, 9, 11, 18, 22, 27, 33, 54, 66, 99, 198, 297, 594

146 : 1, 2, 73, 146

715 : 1, 5, 11, 13, 55, 65, 143, 715

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,273,594,146,715, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

273:3x 7x 13

594:2x 3x 3x 3x 11

146:2x 73

715:5x 11x 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 3x 3x 11x 13 = 5148

Therefore, the value for common factors is 5148.

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 = 10867834537560/(1x5148)

LCM = 10867834537560/5148

LCM = 2111078970

Thus, we can understand that the LCM of 642,273,594,146,715 is 2111078970.
