Given numbers are 260,421,487,442

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

The LCM of 260,421,487,442 is 906219340.

Find LCM of 260,421,487,442 with Prime Factorization

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

2 x 13 x 10 x 421 x 487 x 17 = 906219340

Therefore, the lowest common multiple of 260,421,487,442 is 906219340.

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.

260 x 421 x 487 x 442 = 23561702840

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.

260 : 1, 2, 4, 5, 10, 13, 20, 26, 52, 65, 130, 260

421 : 1, 421

487 : 1, 487

442 : 1, 2, 13, 17, 26, 34, 221, 442

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 260,421,487,442, is 1.

Now, the common factors can be found like this.

260:2x 2x 5x 13

421:421

487:487

442:2x 13x 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 13 = 26

Therefore, the value for common factors is 26.

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 = 23561702840/(1x26)

LCM = 23561702840/26

LCM = 906219340

Thus, we can understand that the LCM of 260,421,487,442 is 906219340.
