Given numbers are 121,364,660,690

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

The LCM of 121,364,660,690 is 15195180.

Find LCM of 121,364,660,690 with Prime Factorization

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

2 x 2 x 3 x 5 x 11 x 1 x 91 x 11 x 23 = 15195180

Therefore, the lowest common multiple of 121,364,660,690 is 15195180.

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 364 x 660 x 690 = 20057637600

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

364 : 1, 2, 4, 7, 13, 14, 26, 28, 52, 91, 182, 364

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,364,660,690, is 1.

Now, the common factors can be found like this.

121:11x 11

364:2x 2x 7x 13

660:2x 2x 3x 5x 11

690:2x 3x 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 2x 2x 3x 5x 11 = 1320

Therefore, the value for common factors is 1320.

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 = 20057637600/(1x1320)

LCM = 20057637600/1320

LCM = 15195180

Thus, we can understand that the LCM of 121,364,660,690 is 15195180.
