Given numbers are 518,742,421,406

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

The LCM of 518,742,421,406 is 335185886.

Find LCM of 518,742,421,406 with Prime Factorization

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

2 x 7 x 37 x 53 x 421 x 29 = 335185886

Therefore, the lowest common multiple of 518,742,421,406 is 335185886.

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.

518 x 742 x 421 x 406 = 65696433656

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.

518 : 1, 2, 7, 14, 37, 74, 259, 518

742 : 1, 2, 7, 14, 53, 106, 371, 742

421 : 1, 421

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 518,742,421,406, is 1.

Now, the common factors can be found like this.

518:2x 7x 37

742:2x 7x 53

421:421

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 7x 7 = 196

Therefore, the value for common factors is 196.

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 = 65696433656/(1x196)

LCM = 65696433656/196

LCM = 335185886

Thus, we can understand that the LCM of 518,742,421,406 is 335185886.
