Given numbers are 393,242,641,570

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

The LCM of 393,242,641,570 is 5791479870.

Find LCM of 393,242,641,570 with Prime Factorization

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

2 x 3 x 131 x 121 x 641 x 95 = 5791479870

Therefore, the lowest common multiple of 393,242,641,570 is 5791479870.

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.

393 x 242 x 641 x 570 = 34748879220

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.

393 : 1, 3, 131, 393

242 : 1, 2, 11, 22, 121, 242

641 : 1, 641

570 : 1, 2, 3, 5, 6, 10, 15, 19, 30, 38, 57, 95, 114, 190, 285, 570

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 393,242,641,570, is 1.

Now, the common factors can be found like this.

393:3x 131

242:2x 11x 11

641:641

570:2x 3x 5x 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 = 34748879220/(1x6)

LCM = 34748879220/6

LCM = 5791479870

Thus, we can understand that the LCM of 393,242,641,570 is 5791479870.
