Given numbers are 156,665,123,939,940
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 156,665,123,939,940 is 62570884740.
Find LCM of 156,665,123,939,940 with Prime Factorization
| 2 | 156, 665, 123, 939, 940 |
| 2 | 78, 665, 123, 939, 470 |
| 3 | 39, 665, 123, 939, 235 |
| 5 | 13, 665, 41, 313, 235 |
| 13, 133, 41, 313, 47 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 13 x 133 x 41 x 313 x 47 = 62570884740
Therefore, the lowest common multiple of 156,665,123,939,940 is 62570884740.
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.
156 x 665 x 123 x 939 x 940 = 11262759253200
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.
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
665 : 1, 5, 7, 19, 35, 95, 133, 665
123 : 1, 3, 41, 123
939 : 1, 3, 313, 939
940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 156,665,123,939,940, is 1.
Now, the common factors can be found like this.
156:2x 2x 3x 13
665:5x 7x 19
123:3x 41
939:3x 313
940:2x 2x 5x 47
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 5 = 180
Therefore, the value for common factors is 180.
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 = 11262759253200/(1x180)
LCM = 11262759253200/180
LCM = 62570884740
Thus, we can understand that the LCM of 156,665,123,939,940 is 62570884740.
