Given numbers are 291,124,788,558,680

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

The LCM of 291,124,788,558,680 is 3625359480.

Find LCM of 291,124,788,558,680 with Prime Factorization

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

2 x 2 x 3 x 31 x 97 x 1 x 197 x 3 x 170 = 3625359480

Therefore, the lowest common multiple of 291,124,788,558,680 is 3625359480.

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.

291 x 124 x 788 x 558 x 680 = 10789069812480

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.

291 : 1, 3, 97, 291

124 : 1, 2, 4, 31, 62, 124

788 : 1, 2, 4, 197, 394, 788

558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558

680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 291,124,788,558,680, is 1.

Now, the common factors can be found like this.

291:3x 97

124:2x 2x 31

788:2x 2x 197

558:2x 3x 3x 31

680:2x 2x 2x 5x 17

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 2x 2x 3x 31 = 2976

Therefore, the value for common factors is 2976.

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 = 10789069812480/(1x2976)

LCM = 10789069812480/2976

LCM = 3625359480

Thus, we can understand that the LCM of 291,124,788,558,680 is 3625359480.
