Given numbers are 303,905,909,402,728
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 303,905,909,402,728 is 40125332520.
Find LCM of 303,905,909,402,728 with Prime Factorization
| 2 | 303, 905, 909, 402, 728 |
| 3 | 303, 905, 909, 201, 364 |
| 101 | 101, 905, 303, 67, 364 |
| 1, 905, 3, 67, 364 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 101 x 1 x 905 x 3 x 67 x 364 = 40125332520
Therefore, the lowest common multiple of 303,905,909,402,728 is 40125332520.
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.
303 x 905 x 909 x 402 x 728 = 72947854521360
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.
303 : 1, 3, 101, 303
905 : 1, 5, 181, 905
909 : 1, 3, 9, 101, 303, 909
402 : 1, 2, 3, 6, 67, 134, 201, 402
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 303,905,909,402,728, is 1.
Now, the common factors can be found like this.
303:3x 101
905:5x 181
909:3x 3x 101
402:2x 3x 67
728:2x 2x 2x 7x 13
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 101 = 1818
Therefore, the value for common factors is 1818.
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 = 72947854521360/(1x1818)
LCM = 72947854521360/1818
LCM = 40125332520
Thus, we can understand that the LCM of 303,905,909,402,728 is 40125332520.
