Given numbers are 688,903,395,559

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

The LCM of 688,903,395,559 is 74190480.

Find LCM of 688,903,395,559 with Prime Factorization

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

43 x 16 x 21 x 395 x 13 = 74190480

Therefore, the lowest common multiple of 688,903,395,559 is 74190480.

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.

688 x 903 x 395 x 559 = 137178197520

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.

688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688

903 : 1, 3, 7, 21, 43, 129, 301, 903

395 : 1, 5, 79, 395

559 : 1, 13, 43, 559

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 688,903,395,559, is 1.

Now, the common factors can be found like this.

688:2x 2x 2x 2x 43

903:3x 7x 43

395:5x 79

559:13x 43

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

43x 43 = 1849

Therefore, the value for common factors is 1849.

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 = 137178197520/(1x1849)

LCM = 137178197520/1849

LCM = 74190480

Thus, we can understand that the LCM of 688,903,395,559 is 74190480.
