Find LCM of 392,231,918,539,765 with Prime Factorization
| 2 | 392, 231, 918, 539, 765 |
| 3 | 196, 231, 459, 539, 765 |
| 3 | 196, 77, 153, 539, 255 |
| 7 | 196, 77, 51, 539, 85 |
| 7 | 28, 11, 51, 77, 85 |
| 11 | 4, 11, 51, 11, 85 |
| 17 | 4, 1, 51, 1, 85 |
| 4, 1, 3, 1, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 7 x 7 x 11 x 17 x 4 x 1 x 3 x 1 x 5 = 9896040
Therefore, the lowest common multiple of 392,231,918,539,765 is 9896040.
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.
392 x 231 x 918 x 539 x 765 = 34276062688560
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.
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
231 : 1, 3, 7, 11, 21, 33, 77, 231
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
539 : 1, 7, 11, 49, 77, 539
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 392,231,918,539,765, is 1.
Now, the common factors can be found like this.
392:2x 2x 2x 7x 7
231:3x 7x 11
918:2x 3x 3x 3x 17
539:7x 7x 11
765:3x 3x 5x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 7x 7x 7x 11x 17 = 3463614
Therefore, the value for common factors is 3463614.
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 = 34276062688560/(1x3463614)
LCM = 34276062688560/3463614
LCM = 9896040
Thus, we can understand that the LCM of 392,231,918,539,765 is 9896040.
