Given numbers are 520,786,290,391,610

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

The LCM of 520,786,290,391,610 is 141351520440.

Find LCM of 520,786,290,391,610 with Prime Factorization

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

2 x 5 x 52 x 393 x 29 x 391 x 61 = 141351520440

Therefore, the lowest common multiple of 520,786,290,391,610 is 141351520440.

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 786 x 290 x 391 x 610 = 28270304088000

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

786 : 1, 2, 3, 6, 131, 262, 393, 786

290 : 1, 2, 5, 10, 29, 58, 145, 290

391 : 1, 17, 23, 391

610 : 1, 2, 5, 10, 61, 122, 305, 610

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 520,786,290,391,610, is 1.

Now, the common factors can be found like this.

520:2x 2x 2x 5x 13

786:2x 3x 131

290:2x 5x 29

391:17x 23

610:2x 5x 61

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 5x 5 = 200

Therefore, the value for common factors is 200.

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 = 28270304088000/(1x200)

LCM = 28270304088000/200

LCM = 141351520440

Thus, we can understand that the LCM of 520,786,290,391,610 is 141351520440.
