Given numbers are 681,443,690,684,977

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

The LCM of 681,443,690,684,977 is 7728195310020.

Find LCM of 681,443,690,684,977 with Prime Factorization

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

2 x 3 x 227 x 443 x 115 x 114 x 977 = 7728195310020

Therefore, the lowest common multiple of 681,443,690,684,977 is 7728195310020.

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.

681 x 443 x 690 x 684 x 977 = 139107515580360

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.

681 : 1, 3, 227, 681

443 : 1, 443

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684

977 : 1, 977

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 681,443,690,684,977, is 1.

Now, the common factors can be found like this.

681:3x 227

443:443

690:2x 3x 5x 23

684:2x 2x 3x 3x 19

977:977

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

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 139107515580360/(1x18)

LCM = 139107515580360/18

LCM = 7728195310020

Thus, we can understand that the LCM of 681,443,690,684,977 is 7728195310020.
