Given numbers are 909,286,623,781
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 909,286,623,781 is 11499429942.
Find LCM of 909,286,623,781 with Prime Factorization
11 | 909, 286, 623, 781 |
909, 26, 623, 71 |
Multiply the prime numbers at the bottom and the left side.
11 x 909 x 26 x 623 x 71 = 11499429942
Therefore, the lowest common multiple of 909,286,623,781 is 11499429942.
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 286 x 623 x 781 = 126493729362
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
286 : 1, 2, 11, 13, 22, 26, 143, 286
623 : 1, 7, 89, 623
781 : 1, 11, 71, 781
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 909,286,623,781, is 1.
Now, the common factors can be found like this.
909:3x 3x 101
286:2x 11x 13
623:7x 89
781:11x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11 = 11
Therefore, the value for common factors is 11.
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 = 126493729362/(1x11)
LCM = 126493729362/11
LCM = 11499429942
Thus, we can understand that the LCM of 909,286,623,781 is 11499429942.
