Given numbers are 390,122,886,628

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

The LCM of 390,122,886,628 is 3309236580.

Find LCM of 390,122,886,628 with Prime Factorization

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

2 x 195 x 61 x 443 x 314 = 3309236580

Therefore, the lowest common multiple of 390,122,886,628 is 3309236580.

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.

390 x 122 x 886 x 628 = 26473892640

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.

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

122 : 1, 2, 61, 122

886 : 1, 2, 443, 886

628 : 1, 2, 4, 157, 314, 628

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 390,122,886,628, is 2.

Now, the common factors can be found like this.

390:2x 3x 5x 13

122:2x 61

886:2x 443

628:2x 2x 157

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 26473892640/(2x4)

LCM = 26473892640/8

LCM = 3309236580

Thus, we can understand that the LCM of 390,122,886,628 is 3309236580.
