Find LCM of 972,494,801,247 with Prime Factorization
| 2 | 972, 494, 801, 247 |
| 3 | 486, 247, 801, 247 |
| 3 | 162, 247, 267, 247 |
| 13 | 54, 247, 89, 247 |
| 19 | 54, 19, 89, 19 |
| 54, 1, 89, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 13 x 19 x 54 x 1 x 89 x 1 = 21367476
Therefore, the lowest common multiple of 972,494,801,247 is 21367476.
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.
972 x 494 x 801 x 247 = 94999798296
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.
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
494 : 1, 2, 13, 19, 26, 38, 247, 494
801 : 1, 3, 9, 89, 267, 801
247 : 1, 13, 19, 247
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 972,494,801,247, is 1.
Now, the common factors can be found like this.
972:2x 2x 3x 3x 3x 3x 3
494:2x 13x 19
801:3x 3x 89
247:13x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 13x 19 = 4446
Therefore, the value for common factors is 4446.
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 = 94999798296/(1x4446)
LCM = 94999798296/4446
LCM = 21367476
Thus, we can understand that the LCM of 972,494,801,247 is 21367476.
