Given numbers are 638,529,970,409

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

The LCM of 638,529,970,409 is 66948584230.

Find LCM of 638,529,970,409 with Prime Factorization

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

2 x 319 x 529 x 485 x 409 = 66948584230

Therefore, the lowest common multiple of 638,529,970,409 is 66948584230.

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.

638 x 529 x 970 x 409 = 133897168460

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.

638 : 1, 2, 11, 22, 29, 58, 319, 638

529 : 1, 23, 529

970 : 1, 2, 5, 10, 97, 194, 485, 970

409 : 1, 409

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,529,970,409, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

529:23x 23

970:2x 5x 97

409:409

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

2 = 2

Therefore, the value for common factors is 2.

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 = 133897168460/(1x2)

LCM = 133897168460/2

LCM = 66948584230

Thus, we can understand that the LCM of 638,529,970,409 is 66948584230.
