Given numbers are 202,400,997,407

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

The LCM of 202,400,997,407 is 16393471600.

Find LCM of 202,400,997,407 with Prime Factorization

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

2 x 101 x 200 x 997 x 407 = 16393471600

Therefore, the lowest common multiple of 202,400,997,407 is 16393471600.

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.

202 x 400 x 997 x 407 = 32786943200

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.

202 : 1, 2, 101, 202

400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400

997 : 1, 997

407 : 1, 11, 37, 407

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 202,400,997,407, is 1.

Now, the common factors can be found like this.

202:2x 101

400:2x 2x 2x 2x 5x 5

997:997

407:11x 37

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 = 32786943200/(1x2)

LCM = 32786943200/2

LCM = 16393471600

Thus, we can understand that the LCM of 202,400,997,407 is 16393471600.
