Given numbers are 240,421,646,882

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

The LCM of 240,421,646,882 is 4797480240.

Find LCM of 240,421,646,882 with Prime Factorization

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

2 x 3 x 40 x 421 x 323 x 147 = 4797480240

Therefore, the lowest common multiple of 240,421,646,882 is 4797480240.

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.

240 x 421 x 646 x 882 = 57569762880

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.

240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240

421 : 1, 421

646 : 1, 2, 17, 19, 34, 38, 323, 646

882 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 49, 63, 98, 126, 147, 294, 441, 882

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 240,421,646,882, is 1.

Now, the common factors can be found like this.

240:2x 2x 2x 2x 3x 5

421:421

646:2x 17x 19

882:2x 3x 3x 7x 7

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 3 = 12

Therefore, the value for common factors is 12.

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 = 57569762880/(1x12)

LCM = 57569762880/12

LCM = 4797480240

Thus, we can understand that the LCM of 240,421,646,882 is 4797480240.
