Find LCM of 816,320,901,751 with Prime Factorization
| 2 | 816, 320, 901, 751 |
| 2 | 408, 160, 901, 751 |
| 2 | 204, 80, 901, 751 |
| 2 | 102, 40, 901, 751 |
| 17 | 51, 20, 901, 751 |
| 3, 20, 53, 751 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 17 x 3 x 20 x 53 x 751 = 649584960
Therefore, the lowest common multiple of 816,320,901,751 is 649584960.
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.
816 x 320 x 901 x 751 = 176687109120
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.
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
901 : 1, 17, 53, 901
751 : 1, 751
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 816,320,901,751, is 1.
Now, the common factors can be found like this.
816:2x 2x 2x 2x 3x 17
320:2x 2x 2x 2x 2x 2x 5
901:17x 53
751:751
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 17 = 272
Therefore, the value for common factors is 272.
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 = 176687109120/(1x272)
LCM = 176687109120/272
LCM = 649584960
Thus, we can understand that the LCM of 816,320,901,751 is 649584960.
