Find LCM of 214,752,688,645 with Prime Factorization
| 2 | 214, 752, 688, 645 |
| 2 | 107, 376, 344, 645 |
| 2 | 107, 188, 172, 645 |
| 2 | 107, 94, 86, 645 |
| 43 | 107, 47, 43, 645 |
| 107, 47, 1, 15 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 43 x 107 x 47 x 1 x 15 = 51899280
Therefore, the lowest common multiple of 214,752,688,645 is 51899280.
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.
214 x 752 x 688 x 645 = 71413409280
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.
214 : 1, 2, 107, 214
752 : 1, 2, 4, 8, 16, 47, 94, 188, 376, 752
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
645 : 1, 3, 5, 15, 43, 129, 215, 645
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 214,752,688,645, is 1.
Now, the common factors can be found like this.
214:2x 107
752:2x 2x 2x 2x 47
688:2x 2x 2x 2x 43
645:3x 5x 43
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 43 = 1376
Therefore, the value for common factors is 1376.
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 = 71413409280/(1x1376)
LCM = 71413409280/1376
LCM = 51899280
Thus, we can understand that the LCM of 214,752,688,645 is 51899280.
