LCM Formula to Find Lowest Common Multiple of 642,975,903,468,129

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 975 x 903 x 468 x 129 = 34124237620200

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

975 : 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975

903 : 1, 3, 7, 21, 43, 129, 301, 903

468 : 1, 2, 3, 4, 6, 9, 12, 13, 18, 26, 36, 39, 52, 78, 117, 156, 234, 468

129 : 1, 3, 43, 129

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,975,903,468,129, is 3.

Now, the common factors can be found like this.

642:2x 3x 107

975:3x 5x 5x 13

903:3x 7x 43

468:2x 2x 3x 3x 13

129:3x 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 3x 3x 3x 13x 43 = 30186

Therefore, the value for common factors is 30186.

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 = 34124237620200/(3x30186)

LCM = 34124237620200/90558

LCM = 376821900

Thus, we can understand that the LCM of 642,975,903,468,129 is 376821900.
