LCM of:

Calculate the LCM of 311,980,983,480

Given numbers are 311,980,983,480

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

The LCM of 311,980,983,480 is 7190369760.

Find LCM of 311,980,983,480 with Prime Factorization


2 311, 980, 983, 480
2 311, 490, 983, 240
5 311, 245, 983, 120
311, 49, 983, 24

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

2 x 2 x 5 x 311 x 49 x 983 x 24 = 7190369760

Therefore, the lowest common multiple of 311,980,983,480 is 7190369760.

LCM Formula to Find Lowest Common Multiple of 311,980,983,480

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.

311 x 980 x 983 x 480 = 143807395200

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.

311 : 1, 311

980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980

983 : 1, 983

480 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 80, 96, 120, 160, 240, 480

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 311,980,983,480, is 1.

Now, the common factors can be found like this.

311:311

980:2x 2x 5x 7x 7

983:983

480:2x 2x 2x 2x 2x 3x 5

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 5 = 20

Therefore, the value for common factors is 20.

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 = 143807395200/(1x20)

LCM = 143807395200/20

LCM = 7190369760

Thus, we can understand that the LCM of 311,980,983,480 is 7190369760.
