Given numbers are 872,542,686,961

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

The LCM of 872,542,686,961 is 77893870376.

Find LCM of 872,542,686,961 with Prime Factorization

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

2 x 436 x 271 x 343 x 961 = 77893870376

Therefore, the lowest common multiple of 872,542,686,961 is 77893870376.

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.

872 x 542 x 686 x 961 = 311575481504

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.

872 : 1, 2, 4, 8, 109, 218, 436, 872

542 : 1, 2, 271, 542

686 : 1, 2, 7, 14, 49, 98, 343, 686

961 : 1, 31, 961

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 872,542,686,961, is 1.

Now, the common factors can be found like this.

872:2x 2x 2x 109

542:2x 271

686:2x 7x 7x 7

961:31x 31

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 311575481504/(1x4)

LCM = 311575481504/4

LCM = 77893870376

Thus, we can understand that the LCM of 872,542,686,961 is 77893870376.
