Find LCM of 543,981,689,728,628 with Prime Factorization
| 2 | 543, 981, 689, 728, 628 |
| 2 | 543, 981, 689, 364, 314 |
| 3 | 543, 981, 689, 182, 157 |
| 13 | 181, 327, 689, 182, 157 |
| 181, 327, 53, 14, 157 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 13 x 181 x 327 x 53 x 14 x 157 = 1075609138968
Therefore, the lowest common multiple of 543,981,689,728,628 is 1075609138968.
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.
543 x 981 x 689 x 728 x 628 = 167795025679008
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.
543 : 1, 3, 181, 543
981 : 1, 3, 9, 109, 327, 981
689 : 1, 13, 53, 689
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
628 : 1, 2, 4, 157, 314, 628
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 543,981,689,728,628, is 1.
Now, the common factors can be found like this.
543:3x 181
981:3x 3x 109
689:13x 53
728:2x 2x 2x 7x 13
628:2x 2x 157
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 3x 13 = 156
Therefore, the value for common factors is 156.
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 = 167795025679008/(1x156)
LCM = 167795025679008/156
LCM = 1075609138968
Thus, we can understand that the LCM of 543,981,689,728,628 is 1075609138968.
