Given numbers are 907,420,555,944,990

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

The LCM of 907,420,555,944,990 is 109770146640.

Find LCM of 907,420,555,944,990 with Prime Factorization

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

2 x 2 x 3 x 5 x 907 x 7 x 37 x 236 x 33 = 109770146640

Therefore, the lowest common multiple of 907,420,555,944,990 is 109770146640.

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.

907 x 420 x 555 x 944 x 990 = 197586263952000

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.

907 : 1, 907

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

555 : 1, 3, 5, 15, 37, 111, 185, 555

944 : 1, 2, 4, 8, 16, 59, 118, 236, 472, 944

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 907,420,555,944,990, is 1.

Now, the common factors can be found like this.

907:907

420:2x 2x 3x 5x 7

555:3x 5x 37

944:2x 2x 2x 2x 59

990:2x 3x 3x 5x 11

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 3x 3x 5x 5 = 1800

Therefore, the value for common factors is 1800.

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 = 197586263952000/(1x1800)

LCM = 197586263952000/1800

LCM = 109770146640

Thus, we can understand that the LCM of 907,420,555,944,990 is 109770146640.
