Find LCM of 665,848,918,765 with Prime Factorization
| 2 | 665, 848, 918, 765 |
| 3 | 665, 424, 459, 765 |
| 3 | 665, 424, 153, 255 |
| 5 | 665, 424, 51, 85 |
| 17 | 133, 424, 51, 17 |
| 133, 424, 3, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 17 x 133 x 424 x 3 x 1 = 258839280
Therefore, the lowest common multiple of 665,848,918,765 is 258839280.
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.
665 x 848 x 918 x 765 = 396024098400
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.
665 : 1, 5, 7, 19, 35, 95, 133, 665
848 : 1, 2, 4, 8, 16, 53, 106, 212, 424, 848
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
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 665,848,918,765, is 1.
Now, the common factors can be found like this.
665:5x 7x 19
848:2x 2x 2x 2x 53
918:2x 3x 3x 3x 17
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 5x 17 = 1530
Therefore, the value for common factors is 1530.
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 = 396024098400/(1x1530)
LCM = 396024098400/1530
LCM = 258839280
Thus, we can understand that the LCM of 665,848,918,765 is 258839280.
