Find LCM of 131,611,921,768,188 with Prime Factorization
| 2 | 131, 611, 921, 768, 188 |
| 2 | 131, 611, 921, 384, 94 |
| 3 | 131, 611, 921, 192, 47 |
| 47 | 131, 611, 307, 64, 47 |
| 131, 13, 307, 64, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 47 x 131 x 13 x 307 x 64 x 1 = 18871746816
Therefore, the lowest common multiple of 131,611,921,768,188 is 18871746816.
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.
131 x 611 x 921 x 768 x 188 = 10643665204224
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.
131 : 1, 131
611 : 1, 13, 47, 611
921 : 1, 3, 307, 921
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
188 : 1, 2, 4, 47, 94, 188
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 131,611,921,768,188, is 1.
Now, the common factors can be found like this.
131:131
611:13x 47
921:3x 307
768:2x 2x 2x 2x 2x 2x 2x 2x 3
188:2x 2x 47
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 47 = 564
Therefore, the value for common factors is 564.
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 = 10643665204224/(1x564)
LCM = 10643665204224/564
LCM = 18871746816
Thus, we can understand that the LCM of 131,611,921,768,188 is 18871746816.
