Find LCM of 909,868,616,588 with Prime Factorization
| 2 | 909, 868, 616, 588 |
| 2 | 909, 434, 308, 294 |
| 3 | 909, 217, 154, 147 |
| 7 | 303, 217, 154, 49 |
| 303, 31, 22, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 303 x 31 x 22 x 7 = 121507848
Therefore, the lowest common multiple of 909,868,616,588 is 121507848.
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.
909 x 868 x 616 x 588 = 285786458496
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.
909 : 1, 3, 9, 101, 303, 909
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
588 : 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 49, 84, 98, 147, 196, 294, 588
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 909,868,616,588, is 1.
Now, the common factors can be found like this.
909:3x 3x 101
868:2x 2x 7x 31
616:2x 2x 2x 7x 11
588:2x 2x 3x 7x 7
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 7x 7 = 2352
Therefore, the value for common factors is 2352.
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 = 285786458496/(1x2352)
LCM = 285786458496/2352
LCM = 121507848
Thus, we can understand that the LCM of 909,868,616,588 is 121507848.
