Given numbers are 518,471,220,321

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

The LCM of 518,471,220,321 is 2871621060.

Find LCM of 518,471,220,321 with Prime Factorization

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

2 x 3 x 259 x 157 x 110 x 107 = 2871621060

Therefore, the lowest common multiple of 518,471,220,321 is 2871621060.

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.

518 x 471 x 220 x 321 = 17229726360

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.

518 : 1, 2, 7, 14, 37, 74, 259, 518

471 : 1, 3, 157, 471

220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220

321 : 1, 3, 107, 321

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 518,471,220,321, is 1.

Now, the common factors can be found like this.

518:2x 7x 37

471:3x 157

220:2x 2x 5x 11

321:3x 107

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 17229726360/(1x6)

LCM = 17229726360/6

LCM = 2871621060

Thus, we can understand that the LCM of 518,471,220,321 is 2871621060.
