Given numbers are 423,994,990,699,387

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

The LCM of 423,994,990,699,387 is 231693482790.

Find LCM of 423,994,990,699,387 with Prime Factorization

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

2 x 3 x 3 x 47 x 497 x 55 x 233 x 43 = 231693482790

Therefore, the lowest common multiple of 423,994,990,699,387 is 231693482790.

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.

423 x 994 x 990 x 699 x 387 = 112603032635940

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.

423 : 1, 3, 9, 47, 141, 423

994 : 1, 2, 7, 14, 71, 142, 497, 994

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

699 : 1, 3, 233, 699

387 : 1, 3, 9, 43, 129, 387

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 423,994,990,699,387, is 1.

Now, the common factors can be found like this.

423:3x 3x 47

994:2x 7x 71

990:2x 3x 3x 5x 11

699:3x 233

387:3x 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 3x 3x 3x 3x 3 = 486

Therefore, the value for common factors is 486.

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 = 112603032635940/(1x486)

LCM = 112603032635940/486

LCM = 231693482790

Thus, we can understand that the LCM of 423,994,990,699,387 is 231693482790.
