Given numbers are 777,142,535,128,790

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

The LCM of 777,142,535,128,790 is 298449056640.

Find LCM of 777,142,535,128,790 with Prime Factorization

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

2 x 5 x 777 x 71 x 107 x 64 x 79 = 298449056640

Therefore, the lowest common multiple of 777,142,535,128,790 is 298449056640.

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 142 x 535 x 128 x 790 = 5968981132800

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

142 : 1, 2, 71, 142

535 : 1, 5, 107, 535

128 : 1, 2, 4, 8, 16, 32, 64, 128

790 : 1, 2, 5, 10, 79, 158, 395, 790

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 777,142,535,128,790, is 1.

Now, the common factors can be found like this.

777:3x 7x 37

142:2x 71

535:5x 107

128:2x 2x 2x 2x 2x 2x 2

790:2x 5x 79

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 5 = 20

Therefore, the value for common factors is 20.

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 = 5968981132800/(1x20)

LCM = 5968981132800/20

LCM = 298449056640

Thus, we can understand that the LCM of 777,142,535,128,790 is 298449056640.
