Given numbers are 216,490,137,554

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

The LCM of 216,490,137,554 is 2008261080.

Find LCM of 216,490,137,554 with Prime Factorization

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

2 x 108 x 245 x 137 x 277 = 2008261080

Therefore, the lowest common multiple of 216,490,137,554 is 2008261080.

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.

216 x 490 x 137 x 554 = 8033044320

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.

216 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 108, 216

490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490

137 : 1, 137

554 : 1, 2, 277, 554

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 216,490,137,554, is 1.

Now, the common factors can be found like this.

216:2x 2x 2x 3x 3x 3

490:2x 5x 7x 7

137:137

554:2x 277

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 8033044320/(1x4)

LCM = 8033044320/4

LCM = 2008261080

Thus, we can understand that the LCM of 216,490,137,554 is 2008261080.
