Find LCM of 728,513,692,672,165 with Prime Factorization
| 2 | 728, 513, 692, 672, 165 |
| 2 | 364, 513, 346, 336, 165 |
| 2 | 182, 513, 173, 168, 165 |
| 3 | 91, 513, 173, 84, 165 |
| 7 | 91, 171, 173, 28, 55 |
| 13, 171, 173, 4, 55 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 13 x 171 x 173 x 4 x 55 = 14214039840
Therefore, the lowest common multiple of 728,513,692,672,165 is 14214039840.
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 513 x 692 x 672 x 165 = 28655504317440
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
513 : 1, 3, 9, 19, 27, 57, 171, 513
692 : 1, 2, 4, 173, 346, 692
672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672
165 : 1, 3, 5, 11, 15, 33, 55, 165
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 728,513,692,672,165, is 1.
Now, the common factors can be found like this.
728:2x 2x 2x 7x 13
513:3x 3x 3x 19
692:2x 2x 173
672:2x 2x 2x 2x 2x 3x 7
165:3x 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 3x 3x 7 = 2016
Therefore, the value for common factors is 2016.
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 = 28655504317440/(1x2016)
LCM = 28655504317440/2016
LCM = 14214039840
Thus, we can understand that the LCM of 728,513,692,672,165 is 14214039840.
