Given numbers are 393,959,690,852,661

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

The LCM of 393,959,690,852,661 is 8136334546620.

Find LCM of 393,959,690,852,661 with Prime Factorization

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

2 x 3 x 131 x 959 x 115 x 142 x 661 = 8136334546620

Therefore, the lowest common multiple of 393,959,690,852,661 is 8136334546620.

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 959 x 690 x 852 x 661 = 146454021839160

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

959 : 1, 7, 137, 959

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

852 : 1, 2, 3, 4, 6, 12, 71, 142, 213, 284, 426, 852

661 : 1, 661

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 393,959,690,852,661, is 1.

Now, the common factors can be found like this.

393:3x 131

959:7x 137

690:2x 3x 5x 23

852:2x 2x 3x 71

661:661

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

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 146454021839160/(1x18)

LCM = 146454021839160/18

LCM = 8136334546620

Thus, we can understand that the LCM of 393,959,690,852,661 is 8136334546620.
