Given numbers are 121,242,590,789,138

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

The LCM of 121,242,590,789,138 is 1295514330.

Find LCM of 121,242,590,789,138 with Prime Factorization

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

2 x 3 x 11 x 11 x 1 x 1 x 295 x 263 x 23 = 1295514330

Therefore, the lowest common multiple of 121,242,590,789,138 is 1295514330.

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 242 x 590 x 789 x 138 = 1881086807160

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

242 : 1, 2, 11, 22, 121, 242

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

789 : 1, 3, 263, 789

138 : 1, 2, 3, 6, 23, 46, 69, 138

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,242,590,789,138, is 1.

Now, the common factors can be found like this.

121:11x 11

242:2x 11x 11

590:2x 5x 59

789:3x 263

138:2x 3x 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 2x 3x 11x 11 = 1452

Therefore, the value for common factors is 1452.

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 = 1881086807160/(1x1452)

LCM = 1881086807160/1452

LCM = 1295514330

Thus, we can understand that the LCM of 121,242,590,789,138 is 1295514330.
