LCM Formula to Find Lowest Common Multiple of 984,689,530,432

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.

984 x 689 x 530 x 432 = 155229384960

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.

984 : 1, 2, 3, 4, 6, 8, 12, 24, 41, 82, 123, 164, 246, 328, 492, 984

689 : 1, 13, 53, 689

530 : 1, 2, 5, 10, 53, 106, 265, 530

432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 984,689,530,432, is 1.

Now, the common factors can be found like this.

984:2x 2x 2x 3x 41

689:13x 53

530:2x 5x 53

432:2x 2x 2x 2x 3x 3x 3

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 3x 53 = 2544

Therefore, the value for common factors is 2544.

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 = 155229384960/(1x2544)

LCM = 155229384960/2544

LCM = 61017840

Thus, we can understand that the LCM of 984,689,530,432 is 61017840.
