Given numbers are 649,706,409,204,421

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

The LCM of 649,706,409,204,421 is 8047388599932.

Find LCM of 649,706,409,204,421 with Prime Factorization

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

2 x 649 x 353 x 409 x 102 x 421 = 8047388599932

Therefore, the lowest common multiple of 649,706,409,204,421 is 8047388599932.

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.

649 x 706 x 409 x 204 x 421 = 16094777199864

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.

649 : 1, 11, 59, 649

706 : 1, 2, 353, 706

409 : 1, 409

204 : 1, 2, 3, 4, 6, 12, 17, 34, 51, 68, 102, 204

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 649,706,409,204,421, is 1.

Now, the common factors can be found like this.

649:11x 59

706:2x 353

409:409

204:2x 2x 3x 17

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.

2 = 2

Therefore, the value for common factors is 2.

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 = 16094777199864/(1x2)

LCM = 16094777199864/2

LCM = 8047388599932

Thus, we can understand that the LCM of 649,706,409,204,421 is 8047388599932.
