Given numbers are 422,678,639,622

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

The LCM of 422,678,639,622 is 9476591094.

Find LCM of 422,678,639,622 with Prime Factorization

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

2 x 3 x 211 x 113 x 213 x 311 = 9476591094

Therefore, the lowest common multiple of 422,678,639,622 is 9476591094.

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.

422 x 678 x 639 x 622 = 113719093128

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.

422 : 1, 2, 211, 422

678 : 1, 2, 3, 6, 113, 226, 339, 678

639 : 1, 3, 9, 71, 213, 639

622 : 1, 2, 311, 622

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 422,678,639,622, is 1.

Now, the common factors can be found like this.

422:2x 211

678:2x 3x 113

639:3x 3x 71

622:2x 311

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 3 = 12

Therefore, the value for common factors is 12.

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 = 113719093128/(1x12)

LCM = 113719093128/12

LCM = 9476591094

Thus, we can understand that the LCM of 422,678,639,622 is 9476591094.
