Given numbers are 753,786,990,381

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

The LCM of 753,786,990,381 is 4134128130.

Find LCM of 753,786,990,381 with Prime Factorization

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

2 x 3 x 251 x 131 x 165 x 127 = 4134128130

Therefore, the lowest common multiple of 753,786,990,381 is 4134128130.

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.

753 x 786 x 990 x 381 = 223242919020

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.

753 : 1, 3, 251, 753

786 : 1, 2, 3, 6, 131, 262, 393, 786

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

381 : 1, 3, 127, 381

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 753,786,990,381, is 3.

Now, the common factors can be found like this.

753:3x 251

786:2x 3x 131

990:2x 3x 3x 5x 11

381:3x 127

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

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 223242919020/(3x18)

LCM = 223242919020/54

LCM = 4134128130

Thus, we can understand that the LCM of 753,786,990,381 is 4134128130.
