The LCM of 747,165,905,538,495 is 4000775130.
Find LCM of 747,165,905,538,495 with Prime Factorization
| 3 | 747, 165, 905, 538, 495 |
| 3 | 249, 55, 905, 538, 165 |
| 5 | 83, 55, 905, 538, 55 |
| 11 | 83, 11, 181, 538, 11 |
| 83, 1, 181, 538, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 11 x 83 x 1 x 181 x 538 x 1 = 4000775130
Therefore, the lowest common multiple of 747,165,905,538,495 is 4000775130.
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.
747 x 165 x 905 x 538 x 495 = 29705755340250
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.
747 : 1, 3, 9, 83, 249, 747
165 : 1, 3, 5, 11, 15, 33, 55, 165
905 : 1, 5, 181, 905
538 : 1, 2, 269, 538
495 : 1, 3, 5, 9, 11, 15, 33, 45, 55, 99, 165, 495
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 747,165,905,538,495, is 1.
Now, the common factors can be found like this.
747:3x 3x 83
165:3x 5x 11
905:5x 181
538:2x 269
495:3x 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.
3x 3x 3x 5x 5x 11 = 7425
Therefore, the value for common factors is 7425.
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 = 29705755340250/(1x7425)
LCM = 29705755340250/7425
LCM = 4000775130
Thus, we can understand that the LCM of 747,165,905,538,495 is 4000775130.
