Given numbers are 406,421,618,292,306

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

The LCM of 406,421,618,292,306 is 393268933764.

Find LCM of 406,421,618,292,306 with Prime Factorization

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

2 x 3 x 203 x 421 x 103 x 146 x 51 = 393268933764

Therefore, the lowest common multiple of 406,421,618,292,306 is 393268933764.

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 421 x 618 x 292 x 306 = 9438454410336

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

421 : 1, 421

618 : 1, 2, 3, 6, 103, 206, 309, 618

292 : 1, 2, 4, 73, 146, 292

306 : 1, 2, 3, 6, 9, 17, 18, 34, 51, 102, 153, 306

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 406,421,618,292,306, is 1.

Now, the common factors can be found like this.

406:2x 7x 29

421:421

618:2x 3x 103

292:2x 2x 73

306:2x 3x 3x 17

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 2x 3 = 24

Therefore, the value for common factors is 24.

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 = 9438454410336/(1x24)

LCM = 9438454410336/24

LCM = 393268933764

Thus, we can understand that the LCM of 406,421,618,292,306 is 393268933764.
