Calculate the LCM of 409,394,855,475

Given numbers are 409,394,855,475

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

The LCM of 409,394,855,475 is 688899150.

Find LCM of 409,394,855,475 with Prime Factorization


5 409, 394, 855, 475
19 409, 394, 171, 95
409, 394, 9, 5

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

5 x 19 x 409 x 394 x 9 x 5 = 688899150

Therefore, the lowest common multiple of 409,394,855,475 is 688899150.

LCM Formula to Find Lowest Common Multiple of 409,394,855,475

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.

409 x 394 x 855 x 475 = 65445419250

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.

409 : 1, 409

394 : 1, 2, 197, 394

855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855

475 : 1, 5, 19, 25, 95, 475

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 409,394,855,475, is 1.

Now, the common factors can be found like this.

409:409

394:2x 197

855:3x 3x 5x 19

475:5x 5x 19

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

5x 19 = 95

Therefore, the value for common factors is 95.

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 = 65445419250/(1x95)

LCM = 65445419250/95

LCM = 688899150

Thus, we can understand that the LCM of 409,394,855,475 is 688899150.
