Given numbers are 497,620,478,558

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

The LCM of 497,620,478,558 is 662809140.

Find LCM of 497,620,478,558 with Prime Factorization

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

2 x 31 x 497 x 10 x 239 x 9 = 662809140

Therefore, the lowest common multiple of 497,620,478,558 is 662809140.

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.

497 x 620 x 478 x 558 = 82188333360

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.

497 : 1, 7, 71, 497

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

478 : 1, 2, 239, 478

558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 497,620,478,558, is 1.

Now, the common factors can be found like this.

497:7x 71

620:2x 2x 5x 31

478:2x 239

558:2x 3x 3x 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 2x 31 = 124

Therefore, the value for common factors is 124.

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 = 82188333360/(1x124)

LCM = 82188333360/124

LCM = 662809140

Thus, we can understand that the LCM of 497,620,478,558 is 662809140.
