Given numbers are 686,203,880,503

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

The LCM of 686,203,880,503 is 4402940080.

Find LCM of 686,203,880,503 with Prime Factorization

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

2 x 7 x 49 x 29 x 440 x 503 = 4402940080

Therefore, the lowest common multiple of 686,203,880,503 is 4402940080.

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 203 x 880 x 503 = 61641161120

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

203 : 1, 7, 29, 203

880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880

503 : 1, 503

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 686,203,880,503, is 1.

Now, the common factors can be found like this.

686:2x 7x 7x 7

203:7x 29

880:2x 2x 2x 2x 5x 11

503:503

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

2x 7 = 14

Therefore, the value for common factors is 14.

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 = 61641161120/(1x14)

LCM = 61641161120/14

LCM = 4402940080

Thus, we can understand that the LCM of 686,203,880,503 is 4402940080.
