LCM Formula to Find Lowest Common Multiple of 642,403,424,686

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.

642 x 403 x 424 x 686 = 75254079264

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.

642 : 1, 2, 3, 6, 107, 214, 321, 642

403 : 1, 13, 31, 403

424 : 1, 2, 4, 8, 53, 106, 212, 424

686 : 1, 2, 7, 14, 49, 98, 343, 686

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,403,424,686, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

403:13x 31

424:2x 2x 2x 53

686:2x 7x 7x 7

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 75254079264/(1x4)

LCM = 75254079264/4

LCM = 18813519816

Thus, we can understand that the LCM of 642,403,424,686 is 18813519816.
