Find LCM of 308,989,315,869,292 with Prime Factorization
| 2 | 308, 989, 315, 869, 292 |
| 2 | 154, 989, 315, 869, 146 |
| 7 | 77, 989, 315, 869, 73 |
| 11 | 11, 989, 45, 869, 73 |
| 1, 989, 45, 79, 73 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 11 x 1 x 989 x 45 x 79 x 73 = 79051383180
Therefore, the lowest common multiple of 308,989,315,869,292 is 79051383180.
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.
308 x 989 x 315 x 869 x 292 = 24347826019440
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.
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
989 : 1, 23, 43, 989
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
869 : 1, 11, 79, 869
292 : 1, 2, 4, 73, 146, 292
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 308,989,315,869,292, is 1.
Now, the common factors can be found like this.
308:2x 2x 7x 11
989:23x 43
315:3x 3x 5x 7
869:11x 79
292:2x 2x 73
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 7x 11 = 308
Therefore, the value for common factors is 308.
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 = 24347826019440/(1x308)
LCM = 24347826019440/308
LCM = 79051383180
Thus, we can understand that the LCM of 308,989,315,869,292 is 79051383180.
