Given numbers are 540,456,161,158

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

The LCM of 540,456,161,158 is 260993880.

Find LCM of 540,456,161,158 with Prime Factorization

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

2 x 2 x 3 x 45 x 38 x 161 x 79 = 260993880

Therefore, the lowest common multiple of 540,456,161,158 is 260993880.

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 456 x 161 x 158 = 6263853120

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

456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456

161 : 1, 7, 23, 161

158 : 1, 2, 79, 158

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 540,456,161,158, is 1.

Now, the common factors can be found like this.

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

456:2x 2x 2x 3x 19

161:7x 23

158:2x 79

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 3 = 24

Therefore, the value for common factors is 24.

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 = 6263853120/(1x24)

LCM = 6263853120/24

LCM = 260993880

Thus, we can understand that the LCM of 540,456,161,158 is 260993880.
