Find LCM of 909,762,553,392,728 with Prime Factorization
| 2 | 909, 762, 553, 392, 728 |
| 2 | 909, 381, 553, 196, 364 |
| 2 | 909, 381, 553, 98, 182 |
| 3 | 909, 381, 553, 49, 91 |
| 7 | 303, 127, 553, 49, 91 |
| 303, 127, 79, 7, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 303 x 127 x 79 x 7 x 13 = 46475504712
Therefore, the lowest common multiple of 909,762,553,392,728 is 46475504712.
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 762 x 553 x 392 x 728 = 109310387082624
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
762 : 1, 2, 3, 6, 127, 254, 381, 762
553 : 1, 7, 79, 553
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 909,762,553,392,728, is 1.
Now, the common factors can be found like this.
909:3x 3x 101
762:2x 3x 127
553:7x 79
392:2x 2x 2x 7x 7
728:2x 2x 2x 7x 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 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 = 109310387082624/(1x2352)
LCM = 109310387082624/2352
LCM = 46475504712
Thus, we can understand that the LCM of 909,762,553,392,728 is 46475504712.
