LCM Formula to Find Lowest Common Multiple of 855,516,155,992

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.

855 x 516 x 155 x 992 = 67835836800

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.

855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855

516 : 1, 2, 3, 4, 6, 12, 43, 86, 129, 172, 258, 516

155 : 1, 5, 31, 155

992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 855,516,155,992, is 1.

Now, the common factors can be found like this.

855:3x 3x 5x 19

516:2x 2x 3x 43

155:5x 31

992:2x 2x 2x 2x 2x 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 5x 31 = 1860

Therefore, the value for common factors is 1860.

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 = 67835836800/(1x1860)

LCM = 67835836800/1860

LCM = 36470880

Thus, we can understand that the LCM of 855,516,155,992 is 36470880.
