Find LCM of 431,118,783,788,396 with Prime Factorization
| 2 | 431, 118, 783, 788, 396 |
| 2 | 431, 59, 783, 394, 198 |
| 3 | 431, 59, 783, 197, 99 |
| 3 | 431, 59, 261, 197, 33 |
| 431, 59, 87, 197, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 431 x 59 x 87 x 197 x 11 = 172587741876
Therefore, the lowest common multiple of 431,118,783,788,396 is 172587741876.
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.
431 x 118 x 783 x 788 x 396 = 12426317415072
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.
431 : 1, 431
118 : 1, 2, 59, 118
783 : 1, 3, 9, 27, 29, 87, 261, 783
788 : 1, 2, 4, 197, 394, 788
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 431,118,783,788,396, is 1.
Now, the common factors can be found like this.
431:431
118:2x 59
783:3x 3x 3x 29
788:2x 2x 197
396:2x 2x 3x 3x 11
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 3 = 72
Therefore, the value for common factors is 72.
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 = 12426317415072/(1x72)
LCM = 12426317415072/72
LCM = 172587741876
Thus, we can understand that the LCM of 431,118,783,788,396 is 172587741876.
