Find LCM of 463,661,792,720,690 with Prime Factorization
| 2 | 463, 661, 792, 720, 690 |
| 2 | 463, 661, 396, 360, 345 |
| 2 | 463, 661, 198, 180, 345 |
| 3 | 463, 661, 99, 90, 345 |
| 3 | 463, 661, 33, 30, 115 |
| 5 | 463, 661, 11, 10, 115 |
| 463, 661, 11, 2, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 5 x 463 x 661 x 11 x 2 x 23 = 55748792880
Therefore, the lowest common multiple of 463,661,792,720,690 is 55748792880.
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.
463 x 661 x 792 x 720 x 690 = 120417392620800
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.
463 : 1, 463
661 : 1, 661
792 : 1, 2, 3, 4, 6, 8, 9, 11, 12, 18, 22, 24, 33, 36, 44, 66, 72, 88, 99, 132, 198, 264, 396, 792
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 463,661,792,720,690, is 1.
Now, the common factors can be found like this.
463:463
661:661
792:2x 2x 2x 3x 3x 11
720:2x 2x 2x 2x 3x 3x 5
690:2x 3x 5x 23
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 3x 3x 3x 5 = 2160
Therefore, the value for common factors is 2160.
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 = 120417392620800/(1x2160)
LCM = 120417392620800/2160
LCM = 55748792880
Thus, we can understand that the LCM of 463,661,792,720,690 is 55748792880.
