Given numbers are 909,902,197,902
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 909,902,197,902 is 161523846.
Find LCM of 909,902,197,902 with Prime Factorization
| 2 | 909, 902, 197, 902 |
| 11 | 909, 451, 197, 451 |
| 41 | 909, 41, 197, 41 |
| 909, 1, 197, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 41 x 909 x 1 x 197 x 1 = 161523846
Therefore, the lowest common multiple of 909,902,197,902 is 161523846.
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.
909 x 902 x 197 x 902 = 145694509092
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.
909 : 1, 3, 9, 101, 303, 909
902 : 1, 2, 11, 22, 41, 82, 451, 902
197 : 1, 197
902 : 1, 2, 11, 22, 41, 82, 451, 902
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 909,902,197,902, is 1.
Now, the common factors can be found like this.
909:3x 3x 101
902:2x 11x 41
197:197
902:2x 11x 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 11x 41 = 902
Therefore, the value for common factors is 902.
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 = 145694509092/(1x902)
LCM = 145694509092/902
LCM = 161523846
Thus, we can understand that the LCM of 909,902,197,902 is 161523846.
