Given numbers are 942,143,780,728

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

The LCM of 942,143,780,728 is 18858840.

Find LCM of 942,143,780,728 with Prime Factorization

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

2 x 2 x 3 x 13 x 157 x 11 x 5 x 14 = 18858840

Therefore, the lowest common multiple of 942,143,780,728 is 18858840.

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 143 x 780 x 728 = 76491455040

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

143 : 1, 11, 13, 143

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

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 942,143,780,728, is 1.

Now, the common factors can be found like this.

942:2x 3x 157

143:11x 13

780:2x 2x 3x 5x 13

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 13x 13 = 4056

Therefore, the value for common factors is 4056.

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 = 76491455040/(1x4056)

LCM = 76491455040/4056

LCM = 18858840

Thus, we can understand that the LCM of 942,143,780,728 is 18858840.
