The LCM of 278,816,903,947,695 is 161655854640.
Find LCM of 278,816,903,947,695 with Prime Factorization
| 2 | 278, 816, 903, 947, 695 |
| 3 | 139, 408, 903, 947, 695 |
| 139 | 139, 136, 301, 947, 695 |
| 1, 136, 301, 947, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 139 x 1 x 136 x 301 x 947 x 5 = 161655854640
Therefore, the lowest common multiple of 278,816,903,947,695 is 161655854640.
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.
278 x 816 x 903 x 947 x 695 = 134820982769760
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.
278 : 1, 2, 139, 278
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
903 : 1, 3, 7, 21, 43, 129, 301, 903
947 : 1, 947
695 : 1, 5, 139, 695
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 278,816,903,947,695, is 1.
Now, the common factors can be found like this.
278:2x 139
816:2x 2x 2x 2x 3x 17
903:3x 7x 43
947:947
695:5x 139
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 139 = 834
Therefore, the value for common factors is 834.
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 = 134820982769760/(1x834)
LCM = 134820982769760/834
LCM = 161655854640
Thus, we can understand that the LCM of 278,816,903,947,695 is 161655854640.
