Given numbers are 686,635,503,508

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

The LCM of 686,635,503,508 is 438223660.

Find LCM of 686,635,503,508 with Prime Factorization

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

2 x 127 x 343 x 5 x 503 x 2 = 438223660

Therefore, the lowest common multiple of 686,635,503,508 is 438223660.

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.

686 x 635 x 503 x 508 = 111308809640

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.

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

635 : 1, 5, 127, 635

503 : 1, 503

508 : 1, 2, 4, 127, 254, 508

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 686,635,503,508, is 1.

Now, the common factors can be found like this.

686:2x 7x 7x 7

635:5x 127

503:503

508:2x 2x 127

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

2x 127 = 254

Therefore, the value for common factors is 254.

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 = 111308809640/(1x254)

LCM = 111308809640/254

LCM = 438223660

Thus, we can understand that the LCM of 686,635,503,508 is 438223660.
