Given numbers are 777,990,418,120

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

The LCM of 777,990,418,120 is 19487160.

Find LCM of 777,990,418,120 with Prime Factorization

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

2 x 3 x 5 x 11 x 259 x 3 x 19 x 4 = 19487160

Therefore, the lowest common multiple of 777,990,418,120 is 19487160.

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.

777 x 990 x 418 x 120 = 38584576800

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.

777 : 1, 3, 7, 21, 37, 111, 259, 777

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

418 : 1, 2, 11, 19, 22, 38, 209, 418

120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 777,990,418,120, is 1.

Now, the common factors can be found like this.

777:3x 7x 37

990:2x 3x 3x 5x 11

418:2x 11x 19

120:2x 2x 2x 3x 5

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 3x 3x 5x 11 = 1980

Therefore, the value for common factors is 1980.

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 = 38584576800/(1x1980)

LCM = 38584576800/1980

LCM = 19487160

Thus, we can understand that the LCM of 777,990,418,120 is 19487160.
