Given numbers are 388,728,673,225,147

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 388,728,673,225,147 is 74851194600.

Find LCM of 388,728,673,225,147 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 2 x 3 x 7 x 97 x 26 x 673 x 75 x 7 = 74851194600

Therefore, the lowest common multiple of 388,728,673,225,147 is 74851194600.

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.

388 x 728 x 673 x 225 x 147 = 6287500346400

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.

388 : 1, 2, 4, 97, 194, 388

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

673 : 1, 673

225 : 1, 3, 5, 9, 15, 25, 45, 75, 225

147 : 1, 3, 7, 21, 49, 147

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 388,728,673,225,147, is 1.

Now, the common factors can be found like this.

388:2x 2x 97

728:2x 2x 2x 7x 13

673:673

225:3x 3x 5x 5

147:3x 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 2x 3x 7 = 84

Therefore, the value for common factors is 84.

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 = 6287500346400/(1x84)

LCM = 6287500346400/84

LCM = 74851194600

Thus, we can understand that the LCM of 388,728,673,225,147 is 74851194600.
