Find LCM of 972,429,351,457 with Prime Factorization
| 3 | 972, 429, 351, 457 |
| 3 | 324, 143, 117, 457 |
| 3 | 108, 143, 39, 457 |
| 13 | 36, 143, 13, 457 |
| 36, 11, 1, 457 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 3 x 13 x 36 x 11 x 1 x 457 = 63521172
Therefore, the lowest common multiple of 972,429,351,457 is 63521172.
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 429 x 351 x 457 = 66887794116
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
429 : 1, 3, 11, 13, 33, 39, 143, 429
351 : 1, 3, 9, 13, 27, 39, 117, 351
457 : 1, 457
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 972,429,351,457, is 1.
Now, the common factors can be found like this.
972:2x 2x 3x 3x 3x 3x 3
429:3x 11x 13
351:3x 3x 3x 13
457:457
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 3x 13 = 1053
Therefore, the value for common factors is 1053.
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 = 66887794116/(1x1053)
LCM = 66887794116/1053
LCM = 63521172
Thus, we can understand that the LCM of 972,429,351,457 is 63521172.
