Given numbers are 390,857,161,322,266

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

The LCM of 390,857,161,322,266 is 1022409570.

Find LCM of 390,857,161,322,266 with Prime Factorization

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

2 x 7 x 23 x 195 x 857 x 1 x 1 x 19 = 1022409570

Therefore, the lowest common multiple of 390,857,161,322,266 is 1022409570.

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 857 x 161 x 322 x 266 = 4609022341560

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

857 : 1, 857

161 : 1, 7, 23, 161

322 : 1, 2, 7, 14, 23, 46, 161, 322

266 : 1, 2, 7, 14, 19, 38, 133, 266

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 390,857,161,322,266, is 1.

Now, the common factors can be found like this.

390:2x 3x 5x 13

857:857

161:7x 23

322:2x 7x 23

266:2x 7x 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 2x 7x 7x 23 = 4508

Therefore, the value for common factors is 4508.

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 = 4609022341560/(1x4508)

LCM = 4609022341560/4508

LCM = 1022409570

Thus, we can understand that the LCM of 390,857,161,322,266 is 1022409570.
