Given numbers are 991,590,720,121

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

The LCM of 991,590,720,121 is 5093819280.

Find LCM of 991,590,720,121 with Prime Factorization

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

2 x 5 x 991 x 59 x 72 x 121 = 5093819280

Therefore, the lowest common multiple of 991,590,720,121 is 5093819280.

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.

991 x 590 x 720 x 121 = 50938192800

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.

991 : 1, 991

590 : 1, 2, 5, 10, 59, 118, 295, 590

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

121 : 1, 11, 121

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,590,720,121, is 1.

Now, the common factors can be found like this.

991:991

590:2x 5x 59

720:2x 2x 2x 2x 3x 3x 5

121:11x 11

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 = 50938192800/(1x10)

LCM = 50938192800/10

LCM = 5093819280

Thus, we can understand that the LCM of 991,590,720,121 is 5093819280.
