LCM Formula to Find Lowest Common Multiple of 312,399,847,488

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.

312 x 399 x 847 x 488 = 51455371968

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.

312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312

399 : 1, 3, 7, 19, 21, 57, 133, 399

847 : 1, 7, 11, 77, 121, 847

488 : 1, 2, 4, 8, 61, 122, 244, 488

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 312,399,847,488, is 1.

Now, the common factors can be found like this.

312:2x 2x 2x 3x 13

399:3x 7x 19

847:7x 11x 11

488:2x 2x 2x 61

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 2x 3x 7 = 168

Therefore, the value for common factors is 168.

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 = 51455371968/(1x168)

LCM = 51455371968/168

LCM = 306281976

Thus, we can understand that the LCM of 312,399,847,488 is 306281976.
