Given numbers are 798,390,356,189,494

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

The LCM of 798,390,356,189,494 is 83095740.

Find LCM of 798,390,356,189,494 with Prime Factorization

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

2 x 3 x 7 x 13 x 19 x 1 x 5 x 178 x 9 x 1 = 83095740

Therefore, the lowest common multiple of 798,390,356,189,494 is 83095740.

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.

798 x 390 x 356 x 189 x 494 = 10344422481120

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.

798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798

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

356 : 1, 2, 4, 89, 178, 356

189 : 1, 3, 7, 9, 21, 27, 63, 189

494 : 1, 2, 13, 19, 26, 38, 247, 494

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 798,390,356,189,494, is 1.

Now, the common factors can be found like this.

798:2x 3x 7x 19

390:2x 3x 5x 13

356:2x 2x 89

189:3x 3x 3x 7

494:2x 13x 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 2x 3x 3x 7x 13x 19 = 124488

Therefore, the value for common factors is 124488.

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 = 10344422481120/(1x124488)

LCM = 10344422481120/124488

LCM = 83095740

Thus, we can understand that the LCM of 798,390,356,189,494 is 83095740.
