Given numbers are 428,649,418,706

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

The LCM of 428,649,418,706 is 1863016804.

Find LCM of 428,649,418,706 with Prime Factorization

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

2 x 11 x 214 x 59 x 19 x 353 = 1863016804

Therefore, the lowest common multiple of 428,649,418,706 is 1863016804.

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.

428 x 649 x 418 x 706 = 81972739376

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.

428 : 1, 2, 4, 107, 214, 428

649 : 1, 11, 59, 649

418 : 1, 2, 11, 19, 22, 38, 209, 418

706 : 1, 2, 353, 706

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 428,649,418,706, is 1.

Now, the common factors can be found like this.

428:2x 2x 107

649:11x 59

418:2x 11x 19

706:2x 353

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 11 = 44

Therefore, the value for common factors is 44.

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 = 81972739376/(1x44)

LCM = 81972739376/44

LCM = 1863016804

Thus, we can understand that the LCM of 428,649,418,706 is 1863016804.
