Given numbers are 728,858,532,638,124

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

The LCM of 728,858,532,638,124 is 410353944.

Find LCM of 728,858,532,638,124 with Prime Factorization

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

2 x 2 x 7 x 11 x 13 x 2 x 3 x 19 x 29 x 31 = 410353944

Therefore, the lowest common multiple of 728,858,532,638,124 is 410353944.

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.

728 x 858 x 532 x 638 x 124 = 26288915068416

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.

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

858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858

532 : 1, 2, 4, 7, 14, 19, 28, 38, 76, 133, 266, 532

638 : 1, 2, 11, 22, 29, 58, 319, 638

124 : 1, 2, 4, 31, 62, 124

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 728,858,532,638,124, is 2.

Now, the common factors can be found like this.

728:2x 2x 2x 7x 13

858:2x 3x 11x 13

532:2x 2x 7x 19

638:2x 11x 29

124:2x 2x 31

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 7x 11x 13 = 32032

Therefore, the value for common factors is 32032.

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 = 26288915068416/(2x32032)

LCM = 26288915068416/64064

LCM = 410353944

Thus, we can understand that the LCM of 728,858,532,638,124 is 410353944.
