Given numbers are 919,985,290,688

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

The LCM of 919,985,290,688 is 18060849680.

Find LCM of 919,985,290,688 with Prime Factorization

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

2 x 5 x 919 x 197 x 29 x 344 = 18060849680

Therefore, the lowest common multiple of 919,985,290,688 is 18060849680.

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.

919 x 985 x 290 x 688 = 180608496800

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.

919 : 1, 919

985 : 1, 5, 197, 985

290 : 1, 2, 5, 10, 29, 58, 145, 290

688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 919,985,290,688, is 1.

Now, the common factors can be found like this.

919:919

985:5x 197

290:2x 5x 29

688:2x 2x 2x 2x 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 5 = 10

Therefore, the value for common factors is 10.

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 = 180608496800/(1x10)

LCM = 180608496800/10

LCM = 18060849680

Thus, we can understand that the LCM of 919,985,290,688 is 18060849680.
