Find LCM of 136,781,306,728,660 with Prime Factorization
2 | 136, 781, 306, 728, 660 |
2 | 68, 781, 153, 364, 330 |
2 | 34, 781, 153, 182, 165 |
3 | 17, 781, 153, 91, 165 |
11 | 17, 781, 51, 91, 55 |
17 | 17, 71, 51, 91, 5 |
1, 71, 3, 91, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 11 x 17 x 1 x 71 x 3 x 91 x 5 = 434954520
Therefore, the lowest common multiple of 136,781,306,728,660 is 434954520.
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.
136 x 781 x 306 x 728 x 660 = 15616607086080
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.
136 : 1, 2, 4, 8, 17, 34, 68, 136
781 : 1, 11, 71, 781
306 : 1, 2, 3, 6, 9, 17, 18, 34, 51, 102, 153, 306
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 136,781,306,728,660, is 1.
Now, the common factors can be found like this.
136:2x 2x 2x 17
781:11x 71
306:2x 3x 3x 17
728:2x 2x 2x 7x 13
660:2x 2x 3x 5x 11
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 2x 2x 3x 11x 17 = 35904
Therefore, the value for common factors is 35904.
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 = 15616607086080/(1x35904)
LCM = 15616607086080/35904
LCM = 434954520
Thus, we can understand that the LCM of 136,781,306,728,660 is 434954520.
