The LCM of 312,518,916,672 is 74020128.
Find LCM of 312,518,916,672 with Prime Factorization
| 2 | 312, 518, 916, 672 |
| 2 | 156, 259, 458, 336 |
| 2 | 78, 259, 229, 168 |
| 3 | 39, 259, 229, 84 |
| 7 | 13, 259, 229, 28 |
| 13, 37, 229, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 13 x 37 x 229 x 4 = 74020128
Therefore, the lowest common multiple of 312,518,916,672 is 74020128.
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.
312 x 518 x 916 x 672 = 99483052032
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.
312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312
518 : 1, 2, 7, 14, 37, 74, 259, 518
916 : 1, 2, 4, 229, 458, 916
672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 312,518,916,672, is 2.
Now, the common factors can be found like this.
312:2x 2x 2x 3x 13
518:2x 7x 37
916:2x 2x 229
672:2x 2x 2x 2x 2x 3x 7
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 2x 3x 7 = 672
Therefore, the value for common factors is 672.
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 = 99483052032/(2x672)
LCM = 99483052032/1344
LCM = 74020128
Thus, we can understand that the LCM of 312,518,916,672 is 74020128.
