The LCM of 309,154,957,899 is 42779814.

Find LCM of 309,154,957,899 with Prime Factorization


3 309, 154, 957, 899
11 103, 154, 319, 899
29 103, 14, 29, 899
103, 14, 1, 31

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

3 x 11 x 29 x 103 x 14 x 1 x 31 = 42779814

Therefore, the lowest common multiple of 309,154,957,899 is 42779814.

LCM Formula to Find Lowest Common Multiple of 309,154,957,899

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.

309 x 154 x 957 x 899 = 40940281998

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.

309 : 1, 3, 103, 309

154 : 1, 2, 7, 11, 14, 22, 77, 154

957 : 1, 3, 11, 29, 33, 87, 319, 957

899 : 1, 29, 31, 899

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 309,154,957,899, is 1.

Now, the common factors can be found like this.

309:3x 103

154:2x 7x 11

957:3x 11x 29

899:29x 31

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

3x 11x 29 = 957

Therefore, the value for common factors is 957.

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 = 40940281998/(1x957)

LCM = 40940281998/957

LCM = 42779814

Thus, we can understand that the LCM of 309,154,957,899 is 42779814.
