Find LCM of 765,242,936,890 with Prime Factorization
| 2 | 765, 242, 936, 890 |
| 3 | 765, 121, 468, 445 |
| 3 | 255, 121, 156, 445 |
| 5 | 85, 121, 52, 445 |
| 17, 121, 52, 89 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 17 x 121 x 52 x 89 = 856781640
Therefore, the lowest common multiple of 765,242,936,890 is 856781640.
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.
765 x 242 x 936 x 890 = 154220695200
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.
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
242 : 1, 2, 11, 22, 121, 242
936 : 1, 2, 3, 4, 6, 8, 9, 12, 13, 18, 24, 26, 36, 39, 52, 72, 78, 104, 117, 156, 234, 312, 468, 936
890 : 1, 2, 5, 10, 89, 178, 445, 890
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 765,242,936,890, is 1.
Now, the common factors can be found like this.
765:3x 3x 5x 17
242:2x 11x 11
936:2x 2x 2x 3x 3x 13
890:2x 5x 89
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 3x 3x 5 = 180
Therefore, the value for common factors is 180.
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 = 154220695200/(1x180)
LCM = 154220695200/180
LCM = 856781640
Thus, we can understand that the LCM of 765,242,936,890 is 856781640.
