Given numbers are 121,646,377,618

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

The LCM of 121,646,377,618 is 9105791838.

Find LCM of 121,646,377,618 with Prime Factorization

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

2 x 121 x 323 x 377 x 309 = 9105791838

Therefore, the lowest common multiple of 121,646,377,618 is 9105791838.

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 646 x 377 x 618 = 18211583676

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

646 : 1, 2, 17, 19, 34, 38, 323, 646

377 : 1, 13, 29, 377

618 : 1, 2, 3, 6, 103, 206, 309, 618

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,646,377,618, is 1.

Now, the common factors can be found like this.

121:11x 11

646:2x 17x 19

377:13x 29

618:2x 3x 103

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2 = 2

Therefore, the value for common factors is 2.

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 = 18211583676/(1x2)

LCM = 18211583676/2

LCM = 9105791838

Thus, we can understand that the LCM of 121,646,377,618 is 9105791838.
