Given numbers are 728,203,749,983,630

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

The LCM of 728,203,749,983,630 is 99926157240.

Find LCM of 728,203,749,983,630 with Prime Factorization

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

2 x 7 x 52 x 29 x 107 x 983 x 45 = 99926157240

Therefore, the lowest common multiple of 728,203,749,983,630 is 99926157240.

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 203 x 749 x 983 x 630 = 68549343866640

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

203 : 1, 7, 29, 203

749 : 1, 7, 107, 749

983 : 1, 983

630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 728,203,749,983,630, is 1.

Now, the common factors can be found like this.

728:2x 2x 2x 7x 13

203:7x 29

749:7x 107

983:983

630:2x 3x 3x 5x 7

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

2x 7x 7x 7 = 686

Therefore, the value for common factors is 686.

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 = 68549343866640/(1x686)

LCM = 68549343866640/686

LCM = 99926157240

Thus, we can understand that the LCM of 728,203,749,983,630 is 99926157240.
