Find LCM of 748,969,692,810,395 with Prime Factorization
| 2 | 748, 969, 692, 810, 395 |
| 2 | 374, 969, 346, 405, 395 |
| 3 | 187, 969, 173, 405, 395 |
| 5 | 187, 323, 173, 135, 395 |
| 17 | 187, 323, 173, 27, 79 |
| 11, 19, 173, 27, 79 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 17 x 11 x 19 x 173 x 27 x 79 = 78665338620
Therefore, the lowest common multiple of 748,969,692,810,395 is 78665338620.
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.
748 x 969 x 692 x 810 x 395 = 160477290784800
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.
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
969 : 1, 3, 17, 19, 51, 57, 323, 969
692 : 1, 2, 4, 173, 346, 692
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
395 : 1, 5, 79, 395
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 748,969,692,810,395, is 1.
Now, the common factors can be found like this.
748:2x 2x 11x 17
969:3x 17x 19
692:2x 2x 173
810:2x 3x 3x 3x 3x 5
395:5x 79
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 3x 5x 17 = 2040
Therefore, the value for common factors is 2040.
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 = 160477290784800/(1x2040)
LCM = 160477290784800/2040
LCM = 78665338620
Thus, we can understand that the LCM of 748,969,692,810,395 is 78665338620.
