Find LCM of 558,314,720,421,955 with Prime Factorization
| 2 | 558, 314, 720, 421, 955 |
| 3 | 279, 157, 360, 421, 955 |
| 3 | 93, 157, 120, 421, 955 |
| 5 | 31, 157, 40, 421, 955 |
| 31, 157, 8, 421, 191 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 31 x 157 x 8 x 421 x 191 = 281779442640
Therefore, the lowest common multiple of 558,314,720,421,955 is 281779442640.
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 314 x 720 x 421 x 955 = 50720299675200
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
314 : 1, 2, 157, 314
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
421 : 1, 421
955 : 1, 5, 191, 955
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 558,314,720,421,955, is 1.
Now, the common factors can be found like this.
558:2x 3x 3x 31
314:2x 157
720:2x 2x 2x 2x 3x 3x 5
421:421
955:5x 191
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 5 = 180
Therefore, the value for common factors is 180.
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 = 50720299675200/(1x180)
LCM = 50720299675200/180
LCM = 281779442640
Thus, we can understand that the LCM of 558,314,720,421,955 is 281779442640.
