Find LCM of 578,278,644,289,956 with Prime Factorization
| 2 | 578, 278, 644, 289, 956 |
| 2 | 289, 139, 322, 289, 478 |
| 17 | 289, 139, 161, 289, 239 |
| 17 | 17, 139, 161, 17, 239 |
| 1, 139, 161, 1, 239 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 17 x 17 x 1 x 139 x 161 x 1 x 239 = 6182959636
Therefore, the lowest common multiple of 578,278,644,289,956 is 6182959636.
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 278 x 644 x 289 x 956 = 28590005356864
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
278 : 1, 2, 139, 278
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
289 : 1, 17, 289
956 : 1, 2, 4, 239, 478, 956
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 578,278,644,289,956, is 1.
Now, the common factors can be found like this.
578:2x 17x 17
278:2x 139
644:2x 2x 7x 23
289:17x 17
956:2x 2x 239
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 2x 17x 17 = 4624
Therefore, the value for common factors is 4624.
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 = 28590005356864/(1x4624)
LCM = 28590005356864/4624
LCM = 6182959636
Thus, we can understand that the LCM of 578,278,644,289,956 is 6182959636.
