Find LCM of 287,861,339,356,487 with Prime Factorization


3 287, 861, 339, 356, 487
7 287, 287, 113, 356, 487
41 41, 41, 113, 356, 487
1, 1, 113, 356, 487

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

3 x 7 x 41 x 1 x 1 x 113 x 356 x 487 = 16867881996

Therefore, the lowest common multiple of 287,861,339,356,487 is 16867881996.

LCM Formula to Find Lowest Common Multiple of 287,861,339,356,487

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 861 x 339 x 356 x 487 = 14523246398556

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

861 : 1, 3, 7, 21, 41, 123, 287, 861

339 : 1, 3, 113, 339

356 : 1, 2, 4, 89, 178, 356

487 : 1, 487

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 287,861,339,356,487, is 1.

Now, the common factors can be found like this.

287:7x 41

861:3x 7x 41

339:3x 113

356:2x 2x 89

487:487

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

3x 7x 41 = 861

Therefore, the value for common factors is 861.

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 = 14523246398556/(1x861)

LCM = 14523246398556/861

LCM = 16867881996

Thus, we can understand that the LCM of 287,861,339,356,487 is 16867881996.
