Given numbers are 721,348,990,774

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

The LCM of 721,348,990,774 is 1780192260.

Find LCM of 721,348,990,774 with Prime Factorization

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

2 x 3 x 3 x 721 x 58 x 55 x 43 = 1780192260

Therefore, the lowest common multiple of 721,348,990,774 is 1780192260.

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.

721 x 348 x 990 x 774 = 192260764080

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.

721 : 1, 7, 103, 721

348 : 1, 2, 3, 4, 6, 12, 29, 58, 87, 116, 174, 348

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

774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,348,990,774, is 1.

Now, the common factors can be found like this.

721:7x 103

348:2x 2x 3x 29

990:2x 3x 3x 5x 11

774:2x 3x 3x 43

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 3x 3x 3 = 108

Therefore, the value for common factors is 108.

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 = 192260764080/(1x108)

LCM = 192260764080/108

LCM = 1780192260

Thus, we can understand that the LCM of 721,348,990,774 is 1780192260.
