LCM Formula to Find Lowest Common Multiple of 648,812,986,684

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.

648 x 812 x 986 x 684 = 354865722624

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.

648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648

812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812

986 : 1, 2, 17, 29, 34, 58, 493, 986

684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 648,812,986,684, is 2.

Now, the common factors can be found like this.

648:2x 2x 2x 3x 3x 3x 3

812:2x 2x 7x 29

986:2x 17x 29

684:2x 2x 3x 3x 19

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 3x 29 = 4176

Therefore, the value for common factors is 4176.

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 = 354865722624/(2x4176)

LCM = 354865722624/8352

LCM = 42488712

Thus, we can understand that the LCM of 648,812,986,684 is 42488712.
