Given numbers are 520,153,122,409

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

The LCM of 520,153,122,409 is 1984942440.

Find LCM of 520,153,122,409 with Prime Factorization

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

2 x 260 x 153 x 61 x 409 = 1984942440

Therefore, the lowest common multiple of 520,153,122,409 is 1984942440.

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 153 x 122 x 409 = 3969884880

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

153 : 1, 3, 9, 17, 51, 153

122 : 1, 2, 61, 122

409 : 1, 409

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 520,153,122,409, is 1.

Now, the common factors can be found like this.

520:2x 2x 2x 5x 13

153:3x 3x 17

122:2x 61

409:409

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

2 = 2

Therefore, the value for common factors is 2.

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 = 3969884880/(1x2)

LCM = 3969884880/2

LCM = 1984942440

Thus, we can understand that the LCM of 520,153,122,409 is 1984942440.
