Given numbers are 281,154,786,942,514

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

The LCM of 281,154,786,942,514 is 686202612018.

Find LCM of 281,154,786,942,514 with Prime Factorization

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

2 x 3 x 281 x 77 x 131 x 157 x 257 = 686202612018

Therefore, the lowest common multiple of 281,154,786,942,514 is 686202612018.

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.

281 x 154 x 786 x 942 x 514 = 16468862688432

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.

281 : 1, 281

154 : 1, 2, 7, 11, 14, 22, 77, 154

786 : 1, 2, 3, 6, 131, 262, 393, 786

942 : 1, 2, 3, 6, 157, 314, 471, 942

514 : 1, 2, 257, 514

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 281,154,786,942,514, is 1.

Now, the common factors can be found like this.

281:281

154:2x 7x 11

786:2x 3x 131

942:2x 3x 157

514:2x 257

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 2x 3 = 24

Therefore, the value for common factors is 24.

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 = 16468862688432/(1x24)

LCM = 16468862688432/24

LCM = 686202612018

Thus, we can understand that the LCM of 281,154,786,942,514 is 686202612018.
