Given numbers are 222,421,626,646

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

The LCM of 222,421,626,646 is 9448914738.

Find LCM of 222,421,626,646 with Prime Factorization

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

2 x 111 x 421 x 313 x 323 = 9448914738

Therefore, the lowest common multiple of 222,421,626,646 is 9448914738.

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.

222 x 421 x 626 x 646 = 37795658952

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.

222 : 1, 2, 3, 6, 37, 74, 111, 222

421 : 1, 421

626 : 1, 2, 313, 626

646 : 1, 2, 17, 19, 34, 38, 323, 646

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 222,421,626,646, is 1.

Now, the common factors can be found like this.

222:2x 3x 37

421:421

626:2x 313

646:2x 17x 19

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 37795658952/(1x4)

LCM = 37795658952/4

LCM = 9448914738

Thus, we can understand that the LCM of 222,421,626,646 is 9448914738.
