Given numbers are 407,989,649,165

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

The LCM of 407,989,649,165 is 356232855.

Find LCM of 407,989,649,165 with Prime Factorization

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

11 x 37 x 989 x 59 x 15 = 356232855

Therefore, the lowest common multiple of 407,989,649,165 is 356232855.

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.

407 x 989 x 649 x 165 = 43104175455

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.

407 : 1, 11, 37, 407

989 : 1, 23, 43, 989

649 : 1, 11, 59, 649

165 : 1, 3, 5, 11, 15, 33, 55, 165

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 407,989,649,165, is 1.

Now, the common factors can be found like this.

407:11x 37

989:23x 43

649:11x 59

165:3x 5x 11

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

11x 11 = 121

Therefore, the value for common factors is 121.

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 = 43104175455/(1x121)

LCM = 43104175455/121

LCM = 356232855

Thus, we can understand that the LCM of 407,989,649,165 is 356232855.
