Given numbers are 406,121,481,392

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

The LCM of 406,121,481,392 is 661628968.

Find LCM of 406,121,481,392 with Prime Factorization

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

2 x 7 x 29 x 121 x 481 x 28 = 661628968

Therefore, the lowest common multiple of 406,121,481,392 is 661628968.

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.

406 x 121 x 481 x 392 = 9262805552

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.

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

121 : 1, 11, 121

481 : 1, 13, 37, 481

392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 406,121,481,392, is 1.

Now, the common factors can be found like this.

406:2x 7x 29

121:11x 11

481:13x 37

392:2x 2x 2x 7x 7

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 7 = 14

Therefore, the value for common factors is 14.

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 = 9262805552/(1x14)

LCM = 9262805552/14

LCM = 661628968

Thus, we can understand that the LCM of 406,121,481,392 is 661628968.
