LCM Formula to Find Lowest Common Multiple of 312,429,140,715

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 429 x 140 x 715 = 13398184800

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

429 : 1, 3, 11, 13, 33, 39, 143, 429

140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140

715 : 1, 5, 11, 13, 55, 65, 143, 715

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 312,429,140,715, is 1.

Now, the common factors can be found like this.

312:2x 2x 2x 3x 13

429:3x 11x 13

140:2x 2x 5x 7

715:5x 11x 13

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 11x 13x 13 = 111540

Therefore, the value for common factors is 111540.

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 = 13398184800/(1x111540)

LCM = 13398184800/111540

LCM = 120120

Thus, we can understand that the LCM of 312,429,140,715 is 120120.
