Given numbers are 638,356,557,212

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

The LCM of 638,356,557,212 is 3352522844.

Find LCM of 638,356,557,212 with Prime Factorization

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

2 x 2 x 319 x 89 x 557 x 53 = 3352522844

Therefore, the lowest common multiple of 638,356,557,212 is 3352522844.

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.

638 x 356 x 557 x 212 = 26820182752

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.

638 : 1, 2, 11, 22, 29, 58, 319, 638

356 : 1, 2, 4, 89, 178, 356

557 : 1, 557

212 : 1, 2, 4, 53, 106, 212

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,356,557,212, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

356:2x 2x 89

557:557

212:2x 2x 53

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 2 = 8

Therefore, the value for common factors is 8.

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 = 26820182752/(1x8)

LCM = 26820182752/8

LCM = 3352522844

Thus, we can understand that the LCM of 638,356,557,212 is 3352522844.
