Calculate the LCM of 484,989,644,380

Given numbers are 484,989,644,380

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

The LCM of 484,989,644,380 is 318319540.

Find LCM of 484,989,644,380 with Prime Factorization


2 484, 989, 644, 380
2 242, 989, 322, 190
23 121, 989, 161, 95
121, 43, 7, 95

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

2 x 2 x 23 x 121 x 43 x 7 x 95 = 318319540

Therefore, the lowest common multiple of 484,989,644,380 is 318319540.

LCM Formula to Find Lowest Common Multiple of 484,989,644,380

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.

484 x 989 x 644 x 380 = 117141590720

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.

484 : 1, 2, 4, 11, 22, 44, 121, 242, 484

989 : 1, 23, 43, 989

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 484,989,644,380, is 1.

Now, the common factors can be found like this.

484:2x 2x 11x 11

989:23x 43

644:2x 2x 7x 23

380:2x 2x 5x 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 23 = 368

Therefore, the value for common factors is 368.

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 = 117141590720/(1x368)

LCM = 117141590720/368

LCM = 318319540

Thus, we can understand that the LCM of 484,989,644,380 is 318319540.
