Find LCM of 342,904,979,861,304 with Prime Factorization
| 2 | 342, 904, 979, 861, 304 |
| 2 | 171, 452, 979, 861, 152 |
| 2 | 171, 226, 979, 861, 76 |
| 3 | 171, 113, 979, 861, 38 |
| 19 | 57, 113, 979, 287, 38 |
| 3, 113, 979, 287, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 19 x 3 x 113 x 979 x 287 x 2 = 86867860464
Therefore, the lowest common multiple of 342,904,979,861,304 is 86867860464.
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.
342 x 904 x 979 x 861 x 304 = 79223488743168
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.
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
904 : 1, 2, 4, 8, 113, 226, 452, 904
979 : 1, 11, 89, 979
861 : 1, 3, 7, 21, 41, 123, 287, 861
304 : 1, 2, 4, 8, 16, 19, 38, 76, 152, 304
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 342,904,979,861,304, is 1.
Now, the common factors can be found like this.
342:2x 3x 3x 19
904:2x 2x 2x 113
979:11x 89
861:3x 7x 41
304:2x 2x 2x 2x 19
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 3x 19 = 912
Therefore, the value for common factors is 912.
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 = 79223488743168/(1x912)
LCM = 79223488743168/912
LCM = 86867860464
Thus, we can understand that the LCM of 342,904,979,861,304 is 86867860464.
