The LCM of 558,242,540,740 is 74944980.
Find LCM of 558,242,540,740 with Prime Factorization
| 2 | 558, 242, 540, 740 |
| 2 | 279, 121, 270, 370 |
| 3 | 279, 121, 135, 185 |
| 3 | 93, 121, 45, 185 |
| 5 | 31, 121, 15, 185 |
| 31, 121, 3, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 31 x 121 x 3 x 37 = 74944980
Therefore, the lowest common multiple of 558,242,540,740 is 74944980.
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.
558 x 242 x 540 x 740 = 53960385600
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.
558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558
242 : 1, 2, 11, 22, 121, 242
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
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 558,242,540,740, is 2.
Now, the common factors can be found like this.
558:2x 3x 3x 31
242:2x 11x 11
540:2x 2x 3x 3x 3x 5
740:2x 2x 5x 37
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 3x 5 = 360
Therefore, the value for common factors is 360.
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 = 53960385600/(2x360)
LCM = 53960385600/720
LCM = 74944980
Thus, we can understand that the LCM of 558,242,540,740 is 74944980.
