Given numbers are 668,221,987,518

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

The LCM of 668,221,987,518 is 5391226932.

Find LCM of 668,221,987,518 with Prime Factorization

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

2 x 7 x 334 x 221 x 141 x 37 = 5391226932

Therefore, the lowest common multiple of 668,221,987,518 is 5391226932.

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.

668 x 221 x 987 x 518 = 75477177048

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.

668 : 1, 2, 4, 167, 334, 668

221 : 1, 13, 17, 221

987 : 1, 3, 7, 21, 47, 141, 329, 987

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,221,987,518, is 1.

Now, the common factors can be found like this.

668:2x 2x 167

221:13x 17

987:3x 7x 47

518:2x 7x 37

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

2x 7 = 14

Therefore, the value for common factors is 14.

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 = 75477177048/(1x14)

LCM = 75477177048/14

LCM = 5391226932

Thus, we can understand that the LCM of 668,221,987,518 is 5391226932.
