Given numbers are 990,524,982,577,643

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

The LCM of 990,524,982,577,643 is 47250321091380.

Find LCM of 990,524,982,577,643 with Prime Factorization

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

2 x 495 x 262 x 491 x 577 x 643 = 47250321091380

Therefore, the lowest common multiple of 990,524,982,577,643 is 47250321091380.

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 524 x 982 x 577 x 643 = 189001284365520

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

524 : 1, 2, 4, 131, 262, 524

982 : 1, 2, 491, 982

577 : 1, 577

643 : 1, 643

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 990,524,982,577,643, is 1.

Now, the common factors can be found like this.

990:2x 3x 3x 5x 11

524:2x 2x 131

982:2x 491

577:577

643:643

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 = 189001284365520/(1x4)

LCM = 189001284365520/4

LCM = 47250321091380

Thus, we can understand that the LCM of 990,524,982,577,643 is 47250321091380.
