Given numbers are 680,985,461,774,406

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

The LCM of 680,985,461,774,406 is 4851578549160.

Find LCM of 680,985,461,774,406 with Prime Factorization

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

2 x 5 x 68 x 197 x 461 x 387 x 203 = 4851578549160

Therefore, the lowest common multiple of 680,985,461,774,406 is 4851578549160.

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.

680 x 985 x 461 x 774 x 406 = 97031570983200

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.

680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680

985 : 1, 5, 197, 985

461 : 1, 461

774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774

406 : 1, 2, 7, 14, 29, 58, 203, 406

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 680,985,461,774,406, is 1.

Now, the common factors can be found like this.

680:2x 2x 2x 5x 17

985:5x 197

461:461

774:2x 3x 3x 43

406:2x 7x 29

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 5 = 20

Therefore, the value for common factors is 20.

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 = 97031570983200/(1x20)

LCM = 97031570983200/20

LCM = 4851578549160

Thus, we can understand that the LCM of 680,985,461,774,406 is 4851578549160.
