Find LCM of 239,887,912,665,640 with Prime Factorization
| 2 | 239, 887, 912, 665, 640 |
| 2 | 239, 887, 456, 665, 320 |
| 2 | 239, 887, 228, 665, 160 |
| 2 | 239, 887, 114, 665, 80 |
| 5 | 239, 887, 57, 665, 40 |
| 19 | 239, 887, 57, 133, 8 |
| 239, 887, 3, 7, 8 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 5 x 19 x 239 x 887 x 3 x 7 x 8 = 54134532480
Therefore, the lowest common multiple of 239,887,912,665,640 is 54134532480.
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.
239 x 887 x 912 x 665 x 640 = 82284489369600
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.
239 : 1, 239
887 : 1, 887
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
665 : 1, 5, 7, 19, 35, 95, 133, 665
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 239,887,912,665,640, is 1.
Now, the common factors can be found like this.
239:239
887:887
912:2x 2x 2x 2x 3x 19
665:5x 7x 19
640:2x 2x 2x 2x 2x 2x 2x 5
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 5x 19 = 1520
Therefore, the value for common factors is 1520.
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 = 82284489369600/(1x1520)
LCM = 82284489369600/1520
LCM = 54134532480
Thus, we can understand that the LCM of 239,887,912,665,640 is 54134532480.
