Given numbers are 648,478,888,663

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

The LCM of 648,478,888,663 is 1266388344.

Find LCM of 648,478,888,663 with Prime Factorization

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

2 x 2 x 2 x 3 x 27 x 239 x 37 x 221 = 1266388344

Therefore, the lowest common multiple of 648,478,888,663 is 1266388344.

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 478 x 888 x 663 = 182359921536

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

478 : 1, 2, 239, 478

888 : 1, 2, 3, 4, 6, 8, 12, 24, 37, 74, 111, 148, 222, 296, 444, 888

663 : 1, 3, 13, 17, 39, 51, 221, 663

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 648,478,888,663, is 1.

Now, the common factors can be found like this.

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

478:2x 239

888:2x 2x 2x 3x 37

663:3x 13x 17

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 3 = 144

Therefore, the value for common factors is 144.

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 = 182359921536/(1x144)

LCM = 182359921536/144

LCM = 1266388344

Thus, we can understand that the LCM of 648,478,888,663 is 1266388344.
