The LCM of 292,545,972,438 is 38671020.
Find LCM of 292,545,972,438 with Prime Factorization
| 2 | 292, 545, 972, 438 |
| 2 | 146, 545, 486, 219 |
| 3 | 73, 545, 243, 219 |
| 73 | 73, 545, 81, 73 |
| 1, 545, 81, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 73 x 1 x 545 x 81 x 1 = 38671020
Therefore, the lowest common multiple of 292,545,972,438 is 38671020.
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.
292 x 545 x 972 x 438 = 67751627040
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.
292 : 1, 2, 4, 73, 146, 292
545 : 1, 5, 109, 545
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
438 : 1, 2, 3, 6, 73, 146, 219, 438
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 292,545,972,438, is 1.
Now, the common factors can be found like this.
292:2x 2x 73
545:5x 109
972:2x 2x 3x 3x 3x 3x 3
438:2x 3x 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 2x 3x 73 = 1752
Therefore, the value for common factors is 1752.
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 = 67751627040/(1x1752)
LCM = 67751627040/1752
LCM = 38671020
Thus, we can understand that the LCM of 292,545,972,438 is 38671020.
