Given numbers are 422,112,238,390

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

The LCM of 422,112,238,390 is 78340080.

Find LCM of 422,112,238,390 with Prime Factorization

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

2 x 7 x 211 x 8 x 17 x 195 = 78340080

Therefore, the lowest common multiple of 422,112,238,390 is 78340080.

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 112 x 238 x 390 = 4387044480

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

112 : 1, 2, 4, 7, 8, 14, 16, 28, 56, 112

238 : 1, 2, 7, 14, 17, 34, 119, 238

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 422,112,238,390, is 2.

Now, the common factors can be found like this.

422:2x 211

112:2x 2x 2x 2x 7

238:2x 7x 17

390:2x 3x 5x 13

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 7 = 28

Therefore, the value for common factors is 28.

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 = 4387044480/(2x28)

LCM = 4387044480/56

LCM = 78340080

Thus, we can understand that the LCM of 422,112,238,390 is 78340080.
