Given numbers are 990,497,428,980

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

The LCM of 990,497,428,980 is 737060940.

Find LCM of 990,497,428,980 with Prime Factorization

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

2 x 2 x 5 x 7 x 99 x 71 x 107 x 7 = 737060940

Therefore, the lowest common multiple of 990,497,428,980 is 737060940.

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 497 x 428 x 980 = 206377063200

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

497 : 1, 7, 71, 497

428 : 1, 2, 4, 107, 214, 428

980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 990,497,428,980, is 1.

Now, the common factors can be found like this.

990:2x 3x 3x 5x 11

497:7x 71

428:2x 2x 107

980:2x 2x 5x 7x 7

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 2x 5x 7 = 280

Therefore, the value for common factors is 280.

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 = 206377063200/(1x280)

LCM = 206377063200/280

LCM = 737060940

Thus, we can understand that the LCM of 990,497,428,980 is 737060940.
