Find LCM of 813,728,926,420,508 with Prime Factorization
| 2 | 813, 728, 926, 420, 508 |
| 2 | 813, 364, 463, 210, 254 |
| 3 | 813, 182, 463, 105, 127 |
| 7 | 271, 182, 463, 35, 127 |
| 271, 26, 463, 5, 127 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 271 x 26 x 463 x 5 x 127 = 174010975320
Therefore, the lowest common multiple of 813,728,926,420,508 is 174010975320.
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.
813 x 728 x 926 x 420 x 508 = 116935375415040
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.
813 : 1, 3, 271, 813
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
926 : 1, 2, 463, 926
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
508 : 1, 2, 4, 127, 254, 508
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 813,728,926,420,508, is 1.
Now, the common factors can be found like this.
813:3x 271
728:2x 2x 2x 7x 13
926:2x 463
420:2x 2x 3x 5x 7
508:2x 2x 127
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 7 = 672
Therefore, the value for common factors is 672.
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 = 116935375415040/(1x672)
LCM = 116935375415040/672
LCM = 174010975320
Thus, we can understand that the LCM of 813,728,926,420,508 is 174010975320.
