Given numbers are 282,656,695,21

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

The LCM of 282,656,695,21 is 449993040.

Find LCM of 282,656,695,21 with Prime Factorization

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

2 x 3 x 47 x 328 x 695 x 7 = 449993040

Therefore, the lowest common multiple of 282,656,695,21 is 449993040.

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.

282 x 656 x 695 x 21 = 2699958240

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.

282 : 1, 2, 3, 6, 47, 94, 141, 282

656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656

695 : 1, 5, 139, 695

21 : 1, 3, 7, 21

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 282,656,695,21, is 1.

Now, the common factors can be found like this.

282:2x 3x 47

656:2x 2x 2x 2x 41

695:5x 139

21:3x 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 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 = 2699958240/(1x6)

LCM = 2699958240/6

LCM = 449993040

Thus, we can understand that the LCM of 282,656,695,21 is 449993040.
