Given numbers are 456,279,990,434

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

The LCM of 456,279,990,434 is 16327080.

Find LCM of 456,279,990,434 with Prime Factorization

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

2 x 3 x 3 x 31 x 76 x 1 x 55 x 7 = 16327080

Therefore, the lowest common multiple of 456,279,990,434 is 16327080.

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.

456 x 279 x 990 x 434 = 54663063840

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.

456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456

279 : 1, 3, 9, 31, 93, 279

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

434 : 1, 2, 7, 14, 31, 62, 217, 434

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 456,279,990,434, is 1.

Now, the common factors can be found like this.

456:2x 2x 2x 3x 19

279:3x 3x 31

990:2x 3x 3x 5x 11

434:2x 7x 31

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 3x 31 = 3348

Therefore, the value for common factors is 3348.

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 = 54663063840/(1x3348)

LCM = 54663063840/3348

LCM = 16327080

Thus, we can understand that the LCM of 456,279,990,434 is 16327080.
