The LCM of 468,782,496,989 is 975692016.

Find LCM of 468,782,496,989 with Prime Factorization


2 468, 782, 496, 989
2 234, 391, 248, 989
23 117, 391, 124, 989
117, 17, 124, 43

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

2 x 2 x 23 x 117 x 17 x 124 x 43 = 975692016

Therefore, the lowest common multiple of 468,782,496,989 is 975692016.

LCM Formula to Find Lowest Common Multiple of 468,782,496,989

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.

468 x 782 x 496 x 989 = 179527330944

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.

468 : 1, 2, 3, 4, 6, 9, 12, 13, 18, 26, 36, 39, 52, 78, 117, 156, 234, 468

782 : 1, 2, 17, 23, 34, 46, 391, 782

496 : 1, 2, 4, 8, 16, 31, 62, 124, 248, 496

989 : 1, 23, 43, 989

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 468,782,496,989, is 1.

Now, the common factors can be found like this.

468:2x 2x 3x 3x 13

782:2x 17x 23

496:2x 2x 2x 2x 31

989:23x 43

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 23 = 184

Therefore, the value for common factors is 184.

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 = 179527330944/(1x184)

LCM = 179527330944/184

LCM = 975692016

Thus, we can understand that the LCM of 468,782,496,989 is 975692016.
