Given numbers are 121,900,997,230

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

The LCM of 121,900,997,230 is 2497185900.

Find LCM of 121,900,997,230 with Prime Factorization

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

2 x 5 x 121 x 90 x 997 x 23 = 2497185900

Therefore, the lowest common multiple of 121,900,997,230 is 2497185900.

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.

121 x 900 x 997 x 230 = 24971859000

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.

121 : 1, 11, 121

900 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 25, 30, 36, 45, 50, 60, 75, 90, 100, 150, 180, 225, 300, 450, 900

997 : 1, 997

230 : 1, 2, 5, 10, 23, 46, 115, 230

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,900,997,230, is 1.

Now, the common factors can be found like this.

121:11x 11

900:2x 2x 3x 3x 5x 5

997:997

230:2x 5x 23

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 24971859000/(1x10)

LCM = 24971859000/10

LCM = 2497185900

Thus, we can understand that the LCM of 121,900,997,230 is 2497185900.
