Given numbers are 138,821,305,912

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

The LCM of 138,821,305,912 is 5252495280.

Find LCM of 138,821,305,912 with Prime Factorization

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

2 x 3 x 23 x 821 x 305 x 152 = 5252495280

Therefore, the lowest common multiple of 138,821,305,912 is 5252495280.

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.

138 x 821 x 305 x 912 = 31514971680

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.

138 : 1, 2, 3, 6, 23, 46, 69, 138

821 : 1, 821

305 : 1, 5, 61, 305

912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 138,821,305,912, is 1.

Now, the common factors can be found like this.

138:2x 3x 23

821:821

305:5x 61

912:2x 2x 2x 2x 3x 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 3 = 6

Therefore, the value for common factors is 6.

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 = 31514971680/(1x6)

LCM = 31514971680/6

LCM = 5252495280

Thus, we can understand that the LCM of 138,821,305,912 is 5252495280.
