Given numbers are 422,269,538,615

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

The LCM of 422,269,538,615 is 69813570.

Find LCM of 422,269,538,615 with Prime Factorization

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

2 x 269 x 211 x 1 x 1 x 615 = 69813570

Therefore, the lowest common multiple of 422,269,538,615 is 69813570.

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 269 x 538 x 615 = 37559700660

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

269 : 1, 269

538 : 1, 2, 269, 538

615 : 1, 3, 5, 15, 41, 123, 205, 615

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 422,269,538,615, is 1.

Now, the common factors can be found like this.

422:2x 211

269:269

538:2x 269

615:3x 5x 41

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

2x 269 = 538

Therefore, the value for common factors is 538.

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 = 37559700660/(1x538)

LCM = 37559700660/538

LCM = 69813570

Thus, we can understand that the LCM of 422,269,538,615 is 69813570.
