Find LCM of 774,390,131,432,189 with Prime Factorization
| 2 | 774, 390, 131, 432, 189 |
| 3 | 387, 195, 131, 216, 189 |
| 3 | 129, 65, 131, 72, 63 |
| 3 | 43, 65, 131, 24, 21 |
| 43, 65, 131, 8, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 43 x 65 x 131 x 8 x 7 = 1107222480
Therefore, the lowest common multiple of 774,390,131,432,189 is 1107222480.
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.
774 x 390 x 131 x 432 x 189 = 3228660751680
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.
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
131 : 1, 131
432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432
189 : 1, 3, 7, 9, 21, 27, 63, 189
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 774,390,131,432,189, is 1.
Now, the common factors can be found like this.
774:2x 3x 3x 43
390:2x 3x 5x 13
131:131
432:2x 2x 2x 2x 3x 3x 3
189:3x 3x 3x 7
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 3x 3x 3x 3 = 2916
Therefore, the value for common factors is 2916.
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 = 3228660751680/(1x2916)
LCM = 3228660751680/2916
LCM = 1107222480
Thus, we can understand that the LCM of 774,390,131,432,189 is 1107222480.
