Given numbers are 622,713,138,215

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

The LCM of 622,713,138,215 is 286048470.

Find LCM of 622,713,138,215 with Prime Factorization

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

2 x 23 x 311 x 31 x 3 x 215 = 286048470

Therefore, the lowest common multiple of 622,713,138,215 is 286048470.

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.

622 x 713 x 138 x 215 = 13158229620

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.

622 : 1, 2, 311, 622

713 : 1, 23, 31, 713

138 : 1, 2, 3, 6, 23, 46, 69, 138

215 : 1, 5, 43, 215

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 622,713,138,215, is 1.

Now, the common factors can be found like this.

622:2x 311

713:23x 31

138:2x 3x 23

215:5x 43

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

2x 23 = 46

Therefore, the value for common factors is 46.

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 = 13158229620/(1x46)

LCM = 13158229620/46

LCM = 286048470

Thus, we can understand that the LCM of 622,713,138,215 is 286048470.
