The LCM of 538,660,440,377,916 is 30655121640.
Find LCM of 538,660,440,377,916 with Prime Factorization
| 2 | 538, 660, 440, 377, 916 |
| 2 | 269, 330, 220, 377, 458 |
| 5 | 269, 165, 110, 377, 229 |
| 11 | 269, 33, 22, 377, 229 |
| 269, 3, 2, 377, 229 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 11 x 269 x 3 x 2 x 377 x 229 = 30655121640
Therefore, the lowest common multiple of 538,660,440,377,916 is 30655121640.
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.
538 x 660 x 440 x 377 x 916 = 53953014086400
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.
538 : 1, 2, 269, 538
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
377 : 1, 13, 29, 377
916 : 1, 2, 4, 229, 458, 916
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 538,660,440,377,916, is 1.
Now, the common factors can be found like this.
538:2x 269
660:2x 2x 3x 5x 11
440:2x 2x 2x 5x 11
377:13x 29
916:2x 2x 229
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 5x 11 = 1760
Therefore, the value for common factors is 1760.
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 = 53953014086400/(1x1760)
LCM = 53953014086400/1760
LCM = 30655121640
Thus, we can understand that the LCM of 538,660,440,377,916 is 30655121640.
