Given numbers are 128,177,921,418,848

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

The LCM of 128,177,921,418,848 is 77044877184.

Find LCM of 128,177,921,418,848 with Prime Factorization

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

2 x 2 x 2 x 2 x 3 x 8 x 59 x 307 x 209 x 53 = 77044877184

Therefore, the lowest common multiple of 128,177,921,418,848 is 77044877184.

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.

128 x 177 x 921 x 418 x 848 = 7396308209664

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.

128 : 1, 2, 4, 8, 16, 32, 64, 128

177 : 1, 3, 59, 177

921 : 1, 3, 307, 921

418 : 1, 2, 11, 19, 22, 38, 209, 418

848 : 1, 2, 4, 8, 16, 53, 106, 212, 424, 848

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,177,921,418,848, is 1.

Now, the common factors can be found like this.

128:2x 2x 2x 2x 2x 2x 2

177:3x 59

921:3x 307

418:2x 11x 19

848:2x 2x 2x 2x 53

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 3 = 96

Therefore, the value for common factors is 96.

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 = 7396308209664/(1x96)

LCM = 7396308209664/96

LCM = 77044877184

Thus, we can understand that the LCM of 128,177,921,418,848 is 77044877184.
