Given numbers are 909,986,905,543
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 909,986,905,543 is 811127970.
Find LCM of 909,986,905,543 with Prime Factorization
| 3 | 909, 986, 905, 543 |
| 181 | 303, 986, 905, 181 |
| 303, 986, 5, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 181 x 303 x 986 x 5 x 1 = 811127970
Therefore, the lowest common multiple of 909,986,905,543 is 811127970.
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 986 x 905 x 543 = 440442487710
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
986 : 1, 2, 17, 29, 34, 58, 493, 986
905 : 1, 5, 181, 905
543 : 1, 3, 181, 543
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 909,986,905,543, is 1.
Now, the common factors can be found like this.
909:3x 3x 101
986:2x 17x 29
905:5x 181
543:3x 181
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 181 = 543
Therefore, the value for common factors is 543.
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 = 440442487710/(1x543)
LCM = 440442487710/543
LCM = 811127970
Thus, we can understand that the LCM of 909,986,905,543 is 811127970.
