The LCM of 228,745,665,608,387 is 1227068640.
Find LCM of 228,745,665,608,387 with Prime Factorization
| 2 | 228, 745, 665, 608, 387 |
| 2 | 114, 745, 665, 304, 387 |
| 3 | 57, 745, 665, 152, 387 |
| 5 | 19, 745, 665, 152, 129 |
| 19 | 19, 149, 133, 152, 129 |
| 1, 149, 7, 8, 129 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 19 x 1 x 149 x 7 x 8 x 129 = 1227068640
Therefore, the lowest common multiple of 228,745,665,608,387 is 1227068640.
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.
228 x 745 x 665 x 608 x 387 = 26578306742400
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.
228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228
745 : 1, 5, 149, 745
665 : 1, 5, 7, 19, 35, 95, 133, 665
608 : 1, 2, 4, 8, 16, 19, 32, 38, 76, 152, 304, 608
387 : 1, 3, 9, 43, 129, 387
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 228,745,665,608,387, is 1.
Now, the common factors can be found like this.
228:2x 2x 3x 19
745:5x 149
665:5x 7x 19
608:2x 2x 2x 2x 2x 19
387:3x 3x 43
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 5x 19x 19 = 21660
Therefore, the value for common factors is 21660.
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 = 26578306742400/(1x21660)
LCM = 26578306742400/21660
LCM = 1227068640
Thus, we can understand that the LCM of 228,745,665,608,387 is 1227068640.
