Given numbers are 426,556,343,406

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

The LCM of 426,556,343,406 is 1178003316.

Find LCM of 426,556,343,406 with Prime Factorization

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

2 x 7 x 213 x 278 x 49 x 29 = 1178003316

Therefore, the lowest common multiple of 426,556,343,406 is 1178003316.

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.

426 x 556 x 343 x 406 = 32984092848

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.

426 : 1, 2, 3, 6, 71, 142, 213, 426

556 : 1, 2, 4, 139, 278, 556

343 : 1, 7, 49, 343

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 426,556,343,406, is 1.

Now, the common factors can be found like this.

426:2x 3x 71

556:2x 2x 139

343:7x 7x 7

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 7 = 28

Therefore, the value for common factors is 28.

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 = 32984092848/(1x28)

LCM = 32984092848/28

LCM = 1178003316

Thus, we can understand that the LCM of 426,556,343,406 is 1178003316.
