Find LCM of 495,428,279,872,655 with Prime Factorization
| 2 | 495, 428, 279, 872, 655 |
| 2 | 495, 214, 279, 436, 655 |
| 3 | 495, 107, 279, 218, 655 |
| 3 | 165, 107, 93, 218, 655 |
| 5 | 55, 107, 31, 218, 655 |
| 11, 107, 31, 218, 131 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 11 x 107 x 31 x 218 x 131 = 187559234280
Therefore, the lowest common multiple of 495,428,279,872,655 is 187559234280.
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.
495 x 428 x 279 x 872 x 655 = 33760662170400
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.
495 : 1, 3, 5, 9, 11, 15, 33, 45, 55, 99, 165, 495
428 : 1, 2, 4, 107, 214, 428
279 : 1, 3, 9, 31, 93, 279
872 : 1, 2, 4, 8, 109, 218, 436, 872
655 : 1, 5, 131, 655
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 495,428,279,872,655, is 1.
Now, the common factors can be found like this.
495:3x 3x 5x 11
428:2x 2x 107
279:3x 3x 31
872:2x 2x 2x 109
655:5x 131
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 3x 3x 5 = 180
Therefore, the value for common factors is 180.
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 = 33760662170400/(1x180)
LCM = 33760662170400/180
LCM = 187559234280
Thus, we can understand that the LCM of 495,428,279,872,655 is 187559234280.
