Given numbers are 990,193,145,604

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

The LCM of 990,193,145,604 is 1673391060.

Find LCM of 990,193,145,604 with Prime Factorization

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

2 x 5 x 99 x 193 x 29 x 302 = 1673391060

Therefore, the lowest common multiple of 990,193,145,604 is 1673391060.

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.

990 x 193 x 145 x 604 = 16733910600

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.

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

193 : 1, 193

145 : 1, 5, 29, 145

604 : 1, 2, 4, 151, 302, 604

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 990,193,145,604, is 1.

Now, the common factors can be found like this.

990:2x 3x 3x 5x 11

193:193

145:5x 29

604:2x 2x 151

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 16733910600/(1x10)

LCM = 16733910600/10

LCM = 1673391060

Thus, we can understand that the LCM of 990,193,145,604 is 1673391060.
