Given numbers are 121,121,439,176,690

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

The LCM of 121,121,439,176,690 is 293216880.

Find LCM of 121,121,439,176,690 with Prime Factorization

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

2 x 11 x 11 x 1 x 1 x 439 x 8 x 345 = 293216880

Therefore, the lowest common multiple of 121,121,439,176,690 is 293216880.

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 121 x 439 x 176 x 690 = 780543334560

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

121 : 1, 11, 121

439 : 1, 439

176 : 1, 2, 4, 8, 11, 16, 22, 44, 88, 176

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 121,121,439,176,690, is 1.

Now, the common factors can be found like this.

121:11x 11

121:11x 11

439:439

176:2x 2x 2x 2x 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 11x 11x 11 = 2662

Therefore, the value for common factors is 2662.

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 = 780543334560/(1x2662)

LCM = 780543334560/2662

LCM = 293216880

Thus, we can understand that the LCM of 121,121,439,176,690 is 293216880.
