Given numbers are 520,160,546,242

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

The LCM of 520,160,546,242 is 5285280.

Find LCM of 520,160,546,242 with Prime Factorization

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

2 x 2 x 2 x 5 x 13 x 1 x 4 x 21 x 121 = 5285280

Therefore, the lowest common multiple of 520,160,546,242 is 5285280.

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.

520 x 160 x 546 x 242 = 10993382400

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.

520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520

160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160

546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546

242 : 1, 2, 11, 22, 121, 242

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 520,160,546,242, is 2.

Now, the common factors can be found like this.

520:2x 2x 2x 5x 13

160:2x 2x 2x 2x 2x 5

546:2x 3x 7x 13

242:2x 11x 11

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 2x 5x 13 = 1040

Therefore, the value for common factors is 1040.

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 = 10993382400/(2x1040)

LCM = 10993382400/2080

LCM = 5285280

Thus, we can understand that the LCM of 520,160,546,242 is 5285280.
