LCM Formula to Find Lowest Common Multiple of 372,992,428,160,645

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.

372 x 992 x 428 x 160 x 645 = 16299642470400

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.

372 : 1, 2, 3, 4, 6, 12, 31, 62, 93, 124, 186, 372

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

428 : 1, 2, 4, 107, 214, 428

160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160

645 : 1, 3, 5, 15, 43, 129, 215, 645

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 372,992,428,160,645, is 1.

Now, the common factors can be found like this.

372:2x 2x 3x 31

992:2x 2x 2x 2x 2x 31

428:2x 2x 107

160:2x 2x 2x 2x 2x 5

645:3x 5x 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 2x 2x 2x 2x 2x 2x 2x 2x 3x 5x 31 = 238080

Therefore, the value for common factors is 238080.

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 = 16299642470400/(1x238080)

LCM = 16299642470400/238080

LCM = 68462880

Thus, we can understand that the LCM of 372,992,428,160,645 is 68462880.
