Find LCM of 156,322,726,192,861 with Prime Factorization
| 2 | 156, 322, 726, 192, 861 |
| 2 | 78, 161, 363, 96, 861 |
| 3 | 39, 161, 363, 48, 861 |
| 7 | 13, 161, 121, 16, 287 |
| 13, 23, 121, 16, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 13 x 23 x 121 x 16 x 41 = 1993607616
Therefore, the lowest common multiple of 156,322,726,192,861 is 1993607616.
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.
156 x 322 x 726 x 192 x 861 = 6028669430784
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.
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
322 : 1, 2, 7, 14, 23, 46, 161, 322
726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726
192 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 192
861 : 1, 3, 7, 21, 41, 123, 287, 861
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 156,322,726,192,861, is 1.
Now, the common factors can be found like this.
156:2x 2x 3x 13
322:2x 7x 23
726:2x 3x 11x 11
192:2x 2x 2x 2x 2x 2x 3
861:3x 7x 41
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 7 = 3024
Therefore, the value for common factors is 3024.
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 = 6028669430784/(1x3024)
LCM = 6028669430784/3024
LCM = 1993607616
Thus, we can understand that the LCM of 156,322,726,192,861 is 1993607616.
