Given numbers are 942,637,540,728

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

The LCM of 942,637,540,728 is 108009720.

Find LCM of 942,637,540,728 with Prime Factorization

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

2 x 2 x 3 x 7 x 13 x 157 x 7 x 45 x 2 = 108009720

Therefore, the lowest common multiple of 942,637,540,728 is 108009720.

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.

942 x 637 x 540 x 728 = 235893228480

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.

942 : 1, 2, 3, 6, 157, 314, 471, 942

637 : 1, 7, 13, 49, 91, 637

540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540

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 942,637,540,728, is 1.

Now, the common factors can be found like this.

942:2x 3x 157

637:7x 7x 13

540:2x 2x 3x 3x 3x 5

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 3x 7x 13 = 2184

Therefore, the value for common factors is 2184.

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 = 235893228480/(1x2184)

LCM = 235893228480/2184

LCM = 108009720

Thus, we can understand that the LCM of 942,637,540,728 is 108009720.
