Find LCM of 428,552,339,791,123 with Prime Factorization
| 2 | 428, 552, 339, 791, 123 |
| 2 | 214, 276, 339, 791, 123 |
| 3 | 107, 138, 339, 791, 123 |
| 113 | 107, 46, 113, 791, 41 |
| 107, 46, 1, 7, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 113 x 107 x 46 x 1 x 7 x 41 = 1915504584
Therefore, the lowest common multiple of 428,552,339,791,123 is 1915504584.
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.
428 x 552 x 339 x 791 x 123 = 7792272647712
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.
428 : 1, 2, 4, 107, 214, 428
552 : 1, 2, 3, 4, 6, 8, 12, 23, 24, 46, 69, 92, 138, 184, 276, 552
339 : 1, 3, 113, 339
791 : 1, 7, 113, 791
123 : 1, 3, 41, 123
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 428,552,339,791,123, is 1.
Now, the common factors can be found like this.
428:2x 2x 107
552:2x 2x 2x 3x 23
339:3x 113
791:7x 113
123:3x 41
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 113 = 4068
Therefore, the value for common factors is 4068.
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 = 7792272647712/(1x4068)
LCM = 7792272647712/4068
LCM = 1915504584
Thus, we can understand that the LCM of 428,552,339,791,123 is 1915504584.
