Given numbers are 878,128,988,754

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

The LCM of 878,128,988,754 is 402503296.

Find LCM of 878,128,988,754 with Prime Factorization

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

2 x 2 x 13 x 439 x 32 x 19 x 29 = 402503296

Therefore, the lowest common multiple of 878,128,988,754 is 402503296.

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.

878 x 128 x 988 x 754 = 83720685568

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.

878 : 1, 2, 439, 878

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

988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988

754 : 1, 2, 13, 26, 29, 58, 377, 754

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 878,128,988,754, is 2.

Now, the common factors can be found like this.

878:2x 439

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

988:2x 2x 13x 19

754:2x 13x 29

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 13 = 104

Therefore, the value for common factors is 104.

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 = 83720685568/(2x104)

LCM = 83720685568/208

LCM = 402503296

Thus, we can understand that the LCM of 878,128,988,754 is 402503296.
