Given numbers are 473,128,391,988,753

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

The LCM of 473,128,391,988,753 is 4402909889664.

Find LCM of 473,128,391,988,753 with Prime Factorization

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

2 x 2 x 473 x 32 x 391 x 247 x 753 = 4402909889664

Therefore, the lowest common multiple of 473,128,391,988,753 is 4402909889664.

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.

473 x 128 x 391 x 988 x 753 = 17611639558656

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.

473 : 1, 11, 43, 473

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

391 : 1, 17, 23, 391

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

753 : 1, 3, 251, 753

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 473,128,391,988,753, is 1.

Now, the common factors can be found like this.

473:11x 43

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

391:17x 23

988:2x 2x 13x 19

753:3x 251

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 = 17611639558656/(1x4)

LCM = 17611639558656/4

LCM = 4402909889664

Thus, we can understand that the LCM of 473,128,391,988,753 is 4402909889664.
