LCM Formula to Find Lowest Common Multiple of 390,743,128,385

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.

390 x 743 x 128 x 385 = 14279865600

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.

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

743 : 1, 743

128 : 1, 2, 4, 8, 16, 32, 64, 128

385 : 1, 5, 7, 11, 35, 55, 77, 385

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 390,743,128,385, is 1.

Now, the common factors can be found like this.

390:2x 3x 5x 13

743:743

128:2x 2x 2x 2x 2x 2x 2

385:5x 7x 11

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 14279865600/(1x10)

LCM = 14279865600/10

LCM = 1427986560

Thus, we can understand that the LCM of 390,743,128,385 is 1427986560.
