Given numbers are 791,942,785,773,903
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 791,942,785,773,903 is 123835550790.
Find LCM of 791,942,785,773,903 with Prime Factorization
| 3 | 791, 942, 785, 773, 903 |
| 7 | 791, 314, 785, 773, 301 |
| 157 | 113, 314, 785, 773, 43 |
| 113, 2, 5, 773, 43 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 157 x 113 x 2 x 5 x 773 x 43 = 123835550790
Therefore, the lowest common multiple of 791,942,785,773,903 is 123835550790.
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.
791 x 942 x 785 x 773 x 903 = 408285810954630
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.
791 : 1, 7, 113, 791
942 : 1, 2, 3, 6, 157, 314, 471, 942
785 : 1, 5, 157, 785
773 : 1, 773
903 : 1, 3, 7, 21, 43, 129, 301, 903
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 791,942,785,773,903, is 1.
Now, the common factors can be found like this.
791:7x 113
942:2x 3x 157
785:5x 157
773:773
903:3x 7x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7x 157 = 3297
Therefore, the value for common factors is 3297.
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 = 408285810954630/(1x3297)
LCM = 408285810954630/3297
LCM = 123835550790
Thus, we can understand that the LCM of 791,942,785,773,903 is 123835550790.
