Find LCM of 728,942,411,659,845 with Prime Factorization
| 2 | 728, 942, 411, 659, 845 |
| 3 | 364, 471, 411, 659, 845 |
| 13 | 364, 157, 137, 659, 845 |
| 28, 157, 137, 659, 65 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 28 x 157 x 137 x 659 x 65 = 2012202224760
Therefore, the lowest common multiple of 728,942,411,659,845 is 2012202224760.
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.
728 x 942 x 411 x 659 x 845 = 156951773531280
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.
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
942 : 1, 2, 3, 6, 157, 314, 471, 942
411 : 1, 3, 137, 411
659 : 1, 659
845 : 1, 5, 13, 65, 169, 845
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 728,942,411,659,845, is 1.
Now, the common factors can be found like this.
728:2x 2x 2x 7x 13
942:2x 3x 157
411:3x 137
659:659
845:5x 13x 13
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 13 = 78
Therefore, the value for common factors is 78.
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 = 156951773531280/(1x78)
LCM = 156951773531280/78
LCM = 2012202224760
Thus, we can understand that the LCM of 728,942,411,659,845 is 2012202224760.
