Given numbers are 668,990,777,414

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

The LCM of 668,990,777,414 is 1969741620.

Find LCM of 668,990,777,414 with Prime Factorization

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

2 x 3 x 3 x 334 x 55 x 259 x 23 = 1969741620

Therefore, the lowest common multiple of 668,990,777,414 is 1969741620.

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 990 x 777 x 414 = 212732094960

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

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

777 : 1, 3, 7, 21, 37, 111, 259, 777

414 : 1, 2, 3, 6, 9, 18, 23, 46, 69, 138, 207, 414

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,990,777,414, is 1.

Now, the common factors can be found like this.

668:2x 2x 167

990:2x 3x 3x 5x 11

777:3x 7x 37

414:2x 3x 3x 23

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 3x 3x 3 = 108

Therefore, the value for common factors is 108.

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 = 212732094960/(1x108)

LCM = 212732094960/108

LCM = 1969741620

Thus, we can understand that the LCM of 668,990,777,414 is 1969741620.
