Find LCM of 578,727,161,891,238 with Prime Factorization
| 2 | 578, 727, 161, 891, 238 |
| 7 | 289, 727, 161, 891, 119 |
| 17 | 289, 727, 23, 891, 17 |
| 1, 727, 23, 891, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 17 x 1 x 727 x 23 x 891 x 17 = 60278970906
Therefore, the lowest common multiple of 578,727,161,891,238 is 60278970906.
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.
578 x 727 x 161 x 891 x 238 = 14346395075628
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.
578 : 1, 2, 17, 34, 289, 578
727 : 1, 727
161 : 1, 7, 23, 161
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
238 : 1, 2, 7, 14, 17, 34, 119, 238
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 578,727,161,891,238, is 1.
Now, the common factors can be found like this.
578:2x 17x 17
727:727
161:7x 23
891:3x 3x 3x 3x 11
238:2x 7x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 17 = 238
Therefore, the value for common factors is 238.
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 = 14346395075628/(1x238)
LCM = 14346395075628/238
LCM = 60278970906
Thus, we can understand that the LCM of 578,727,161,891,238 is 60278970906.
