Given numbers are 540,831,128,174

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

The LCM of 540,831,128,174 is 138810240.

Find LCM of 540,831,128,174 with Prime Factorization

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

2 x 2 x 3 x 45 x 277 x 32 x 29 = 138810240

Therefore, the lowest common multiple of 540,831,128,174 is 138810240.

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.

540 x 831 x 128 x 174 = 9994337280

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.

540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540

831 : 1, 3, 277, 831

128 : 1, 2, 4, 8, 16, 32, 64, 128

174 : 1, 2, 3, 6, 29, 58, 87, 174

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 540,831,128,174, is 1.

Now, the common factors can be found like this.

540:2x 2x 3x 3x 3x 5

831:3x 277

128:2x 2x 2x 2x 2x 2x 2

174:2x 3x 29

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 2x 3x 3 = 72

Therefore, the value for common factors is 72.

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 = 9994337280/(1x72)

LCM = 9994337280/72

LCM = 138810240

Thus, we can understand that the LCM of 540,831,128,174 is 138810240.
