Given numbers are 520,135,431,278

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

The LCM of 520,135,431,278 is 841122360.

Find LCM of 520,135,431,278 with Prime Factorization

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

2 x 5 x 52 x 27 x 431 x 139 = 841122360

Therefore, the lowest common multiple of 520,135,431,278 is 841122360.

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.

520 x 135 x 431 x 278 = 8411223600

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.

520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520

135 : 1, 3, 5, 9, 15, 27, 45, 135

431 : 1, 431

278 : 1, 2, 139, 278

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 520,135,431,278, is 1.

Now, the common factors can be found like this.

520:2x 2x 2x 5x 13

135:3x 3x 3x 5

431:431

278:2x 139

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 8411223600/(1x10)

LCM = 8411223600/10

LCM = 841122360

Thus, we can understand that the LCM of 520,135,431,278 is 841122360.
