Given numbers are 310,622,638,248

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

The LCM of 310,622,638,248 is 123019160.

Find LCM of 310,622,638,248 with Prime Factorization

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

2 x 31 x 5 x 311 x 319 x 4 = 123019160

Therefore, the lowest common multiple of 310,622,638,248 is 123019160.

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.

310 x 622 x 638 x 248 = 30508751680

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.

310 : 1, 2, 5, 10, 31, 62, 155, 310

622 : 1, 2, 311, 622

638 : 1, 2, 11, 22, 29, 58, 319, 638

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

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 310,622,638,248, is 2.

Now, the common factors can be found like this.

310:2x 5x 31

622:2x 311

638:2x 11x 29

248:2x 2x 2x 31

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 31 = 124

Therefore, the value for common factors is 124.

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 = 30508751680/(2x124)

LCM = 30508751680/248

LCM = 123019160

Thus, we can understand that the LCM of 310,622,638,248 is 123019160.
