Find LCM of 407,189,122,756,123 with Prime Factorization
2 | 407, 189, 122, 756, 123 |
3 | 407, 189, 61, 378, 123 |
3 | 407, 63, 61, 126, 41 |
3 | 407, 21, 61, 42, 41 |
7 | 407, 7, 61, 14, 41 |
407, 1, 61, 2, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 7 x 407 x 1 x 61 x 2 x 41 = 769537692
Therefore, the lowest common multiple of 407,189,122,756,123 is 769537692.
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.
407 x 189 x 122 x 756 x 123 = 872655742728
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.
407 : 1, 11, 37, 407
189 : 1, 3, 7, 9, 21, 27, 63, 189
122 : 1, 2, 61, 122
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
123 : 1, 3, 41, 123
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 407,189,122,756,123, is 1.
Now, the common factors can be found like this.
407:11x 37
189:3x 3x 3x 7
122:2x 61
756:2x 2x 3x 3x 3x 7
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 3x 3x 3x 3x 7 = 1134
Therefore, the value for common factors is 1134.
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 = 872655742728/(1x1134)
LCM = 872655742728/1134
LCM = 769537692
Thus, we can understand that the LCM of 407,189,122,756,123 is 769537692.
