Given numbers are 518,186,556,821

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

The LCM of 518,186,556,821 is 10995137412.

Find LCM of 518,186,556,821 with Prime Factorization

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

2 x 259 x 93 x 278 x 821 = 10995137412

Therefore, the lowest common multiple of 518,186,556,821 is 10995137412.

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 186 x 556 x 821 = 43980549648

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

186 : 1, 2, 3, 6, 31, 62, 93, 186

556 : 1, 2, 4, 139, 278, 556

821 : 1, 821

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 518,186,556,821, is 1.

Now, the common factors can be found like this.

518:2x 7x 37

186:2x 3x 31

556:2x 2x 139

821:821

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 43980549648/(1x4)

LCM = 43980549648/4

LCM = 10995137412

Thus, we can understand that the LCM of 518,186,556,821 is 10995137412.
