The LCM of 649,671,312,912 is 469367184.
Find LCM of 649,671,312,912 with Prime Factorization
| 2 | 649, 671, 312, 912 |
| 2 | 649, 671, 156, 456 |
| 2 | 649, 671, 78, 228 |
| 3 | 649, 671, 39, 114 |
| 11 | 649, 671, 13, 38 |
| 59, 61, 13, 38 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 11 x 59 x 61 x 13 x 38 = 469367184
Therefore, the lowest common multiple of 649,671,312,912 is 469367184.
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.
649 x 671 x 312 x 912 = 123912936576
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.
649 : 1, 11, 59, 649
671 : 1, 11, 61, 671
312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 649,671,312,912, is 1.
Now, the common factors can be found like this.
649:11x 59
671:11x 61
312:2x 2x 2x 3x 13
912:2x 2x 2x 2x 3x 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 3x 11 = 264
Therefore, the value for common factors is 264.
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 = 123912936576/(1x264)
LCM = 123912936576/264
LCM = 469367184
Thus, we can understand that the LCM of 649,671,312,912 is 469367184.
