The LCM of 542,440,611,495,521 is 341620095960.
Find LCM of 542,440,611,495,521 with Prime Factorization
| 2 | 542, 440, 611, 495, 521 |
| 5 | 271, 220, 611, 495, 521 |
| 11 | 271, 44, 611, 99, 521 |
| 271, 4, 611, 9, 521 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 271 x 4 x 611 x 9 x 521 = 341620095960
Therefore, the lowest common multiple of 542,440,611,495,521 is 341620095960.
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.
542 x 440 x 611 x 495 x 521 = 37578210555600
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.
542 : 1, 2, 271, 542
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
611 : 1, 13, 47, 611
495 : 1, 3, 5, 9, 11, 15, 33, 45, 55, 99, 165, 495
521 : 1, 521
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 542,440,611,495,521, is 1.
Now, the common factors can be found like this.
542:2x 271
440:2x 2x 2x 5x 11
611:13x 47
495:3x 3x 5x 11
521:521
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 11 = 110
Therefore, the value for common factors is 110.
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 = 37578210555600/(1x110)
LCM = 37578210555600/110
LCM = 341620095960
Thus, we can understand that the LCM of 542,440,611,495,521 is 341620095960.
