Given numbers are 406,842,295,780

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

The LCM of 406,842,295,780 is 3933007260.

Find LCM of 406,842,295,780 with Prime Factorization

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

2 x 5 x 203 x 421 x 59 x 78 = 3933007260

Therefore, the lowest common multiple of 406,842,295,780 is 3933007260.

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 842 x 295 x 780 = 78660145200

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

842 : 1, 2, 421, 842

295 : 1, 5, 59, 295

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 406,842,295,780, is 1.

Now, the common factors can be found like this.

406:2x 7x 29

842:2x 421

295:5x 59

780:2x 2x 3x 5x 13

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 5 = 20

Therefore, the value for common factors is 20.

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 = 78660145200/(1x20)

LCM = 78660145200/20

LCM = 3933007260

Thus, we can understand that the LCM of 406,842,295,780 is 3933007260.
