The LCM of 918,309,771,238,745 is 126726471270.
Find LCM of 918,309,771,238,745 with Prime Factorization
| 2 | 918, 309, 771, 238, 745 |
| 3 | 459, 309, 771, 119, 745 |
| 17 | 153, 103, 257, 119, 745 |
| 9, 103, 257, 7, 745 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 9 x 103 x 257 x 7 x 745 = 126726471270
Therefore, the lowest common multiple of 918,309,771,238,745 is 126726471270.
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.
918 x 309 x 771 x 238 x 745 = 38778300208620
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.
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
309 : 1, 3, 103, 309
771 : 1, 3, 257, 771
238 : 1, 2, 7, 14, 17, 34, 119, 238
745 : 1, 5, 149, 745
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 918,309,771,238,745, is 1.
Now, the common factors can be found like this.
918:2x 3x 3x 3x 17
309:3x 103
771:3x 257
238:2x 7x 17
745:5x 149
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 17 = 306
Therefore, the value for common factors is 306.
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 = 38778300208620/(1x306)
LCM = 38778300208620/306
LCM = 126726471270
Thus, we can understand that the LCM of 918,309,771,238,745 is 126726471270.
