Given numbers are 683,374,681,648,421

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

The LCM of 683,374,681,648,421 is 7909431498936.

Find LCM of 683,374,681,648,421 with Prime Factorization

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

2 x 3 x 683 x 187 x 227 x 108 x 421 = 7909431498936

Therefore, the lowest common multiple of 683,374,681,648,421 is 7909431498936.

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.

683 x 374 x 681 x 648 x 421 = 47456588993616

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.

683 : 1, 683

374 : 1, 2, 11, 17, 22, 34, 187, 374

681 : 1, 3, 227, 681

648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 683,374,681,648,421, is 1.

Now, the common factors can be found like this.

683:683

374:2x 11x 17

681:3x 227

648:2x 2x 2x 3x 3x 3x 3

421:421

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 47456588993616/(1x6)

LCM = 47456588993616/6

LCM = 7909431498936

Thus, we can understand that the LCM of 683,374,681,648,421 is 7909431498936.
