Given numbers are 720,605,526,542

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

The LCM of 720,605,526,542 is 6209303760.

Find LCM of 720,605,526,542 with Prime Factorization

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

2 x 5 x 72 x 121 x 263 x 271 = 6209303760

Therefore, the lowest common multiple of 720,605,526,542 is 6209303760.

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.

720 x 605 x 526 x 542 = 124186075200

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.

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

605 : 1, 5, 11, 55, 121, 605

526 : 1, 2, 263, 526

542 : 1, 2, 271, 542

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 720,605,526,542, is 1.

Now, the common factors can be found like this.

720:2x 2x 2x 2x 3x 3x 5

605:5x 11x 11

526:2x 263

542:2x 271

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 5 = 20

Therefore, the value for common factors is 20.

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 = 124186075200/(1x20)

LCM = 124186075200/20

LCM = 6209303760

Thus, we can understand that the LCM of 720,605,526,542 is 6209303760.
