Given numbers are 869,990,572,398,728

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

The LCM of 869,990,572,398,728 is 5665219560.

Find LCM of 869,990,572,398,728 with Prime Factorization

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

2 x 2 x 11 x 13 x 79 x 45 x 1 x 199 x 14 = 5665219560

Therefore, the lowest common multiple of 869,990,572,398,728 is 5665219560.

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.

869 x 990 x 572 x 398 x 728 = 142582245886080

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.

869 : 1, 11, 79, 869

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

572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572

398 : 1, 2, 199, 398

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 869,990,572,398,728, is 1.

Now, the common factors can be found like this.

869:11x 79

990:2x 3x 3x 5x 11

572:2x 2x 11x 13

398:2x 199

728:2x 2x 2x 7x 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 2x 2x 11x 11x 13 = 25168

Therefore, the value for common factors is 25168.

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 = 142582245886080/(1x25168)

LCM = 142582245886080/25168

LCM = 5665219560

Thus, we can understand that the LCM of 869,990,572,398,728 is 5665219560.
