Given numbers are 287,406,238,556,669

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

The LCM of 287,406,238,556,669 is 52629558324.

Find LCM of 287,406,238,556,669 with Prime Factorization

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

2 x 7 x 41 x 29 x 17 x 278 x 669 = 52629558324

Therefore, the lowest common multiple of 287,406,238,556,669 is 52629558324.

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.

287 x 406 x 238 x 556 x 669 = 10315393431504

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.

287 : 1, 7, 41, 287

406 : 1, 2, 7, 14, 29, 58, 203, 406

238 : 1, 2, 7, 14, 17, 34, 119, 238

556 : 1, 2, 4, 139, 278, 556

669 : 1, 3, 223, 669

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 287,406,238,556,669, is 1.

Now, the common factors can be found like this.

287:7x 41

406:2x 7x 29

238:2x 7x 17

556:2x 2x 139

669:3x 223

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 7x 7 = 196

Therefore, the value for common factors is 196.

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 = 10315393431504/(1x196)

LCM = 10315393431504/196

LCM = 52629558324

Thus, we can understand that the LCM of 287,406,238,556,669 is 52629558324.
