Given numbers are 121,969,238,446

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

The LCM of 121,969,238,446 is 366051378.

Find LCM of 121,969,238,446 with Prime Factorization

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

2 x 17 x 121 x 57 x 7 x 223 = 366051378

Therefore, the lowest common multiple of 121,969,238,446 is 366051378.

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 969 x 238 x 446 = 12445746852

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

969 : 1, 3, 17, 19, 51, 57, 323, 969

238 : 1, 2, 7, 14, 17, 34, 119, 238

446 : 1, 2, 223, 446

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,969,238,446, is 1.

Now, the common factors can be found like this.

121:11x 11

969:3x 17x 19

238:2x 7x 17

446:2x 223

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

2x 17 = 34

Therefore, the value for common factors is 34.

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 = 12445746852/(1x34)

LCM = 12445746852/34

LCM = 366051378

Thus, we can understand that the LCM of 121,969,238,446 is 366051378.
