Given numbers are 558,814,549,720
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 558,814,549,720 is 554138640.
Find LCM of 558,814,549,720 with Prime Factorization
| 2 | 558, 814, 549, 720 |
| 3 | 279, 407, 549, 360 |
| 3 | 93, 407, 183, 120 |
| 31, 407, 61, 40 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 31 x 407 x 61 x 40 = 554138640
Therefore, the lowest common multiple of 558,814,549,720 is 554138640.
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 814 x 549 x 720 = 179540919360
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
814 : 1, 2, 11, 22, 37, 74, 407, 814
549 : 1, 3, 9, 61, 183, 549
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 558,814,549,720, is 1.
Now, the common factors can be found like this.
558:2x 3x 3x 31
814:2x 11x 37
549:3x 3x 61
720:2x 2x 2x 2x 3x 3x 5
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 3x 3x 3x 3 = 324
Therefore, the value for common factors is 324.
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 = 179540919360/(1x324)
LCM = 179540919360/324
LCM = 554138640
Thus, we can understand that the LCM of 558,814,549,720 is 554138640.
