Given numbers are 715,650,990,424

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

The LCM of 715,650,990,424 is 13642200.

Find LCM of 715,650,990,424 with Prime Factorization

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

2 x 5 x 11 x 13 x 1 x 5 x 9 x 212 = 13642200

Therefore, the lowest common multiple of 715,650,990,424 is 13642200.

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.

715 x 650 x 990 x 424 = 195083460000

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.

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

650 : 1, 2, 5, 10, 13, 25, 26, 50, 65, 130, 325, 650

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

424 : 1, 2, 4, 8, 53, 106, 212, 424

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 715,650,990,424, is 1.

Now, the common factors can be found like this.

715:5x 11x 13

650:2x 5x 5x 13

990:2x 3x 3x 5x 11

424:2x 2x 2x 53

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 5x 5x 11x 13 = 14300

Therefore, the value for common factors is 14300.

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 = 195083460000/(1x14300)

LCM = 195083460000/14300

LCM = 13642200

Thus, we can understand that the LCM of 715,650,990,424 is 13642200.
