Given numbers are 775,638,218,406

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

The LCM of 775,638,218,406 is 377265350.

Find LCM of 775,638,218,406 with Prime Factorization

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

2 x 29 x 775 x 11 x 109 x 7 = 377265350

Therefore, the lowest common multiple of 775,638,218,406 is 377265350.

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.

775 x 638 x 218 x 406 = 43762780600

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.

775 : 1, 5, 25, 31, 155, 775

638 : 1, 2, 11, 22, 29, 58, 319, 638

218 : 1, 2, 109, 218

406 : 1, 2, 7, 14, 29, 58, 203, 406

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 775,638,218,406, is 1.

Now, the common factors can be found like this.

775:5x 5x 31

638:2x 11x 29

218:2x 109

406:2x 7x 29

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 29 = 116

Therefore, the value for common factors is 116.

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 = 43762780600/(1x116)

LCM = 43762780600/116

LCM = 377265350

Thus, we can understand that the LCM of 775,638,218,406 is 377265350.
