Given numbers are 243,965,946,781
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 243,965,946,781 is 15750091170.
Find LCM of 243,965,946,781 with Prime Factorization
11 | 243, 965, 946, 781 |
243, 965, 86, 71 |
Multiply the prime numbers at the bottom and the left side.
11 x 243 x 965 x 86 x 71 = 15750091170
Therefore, the lowest common multiple of 243,965,946,781 is 15750091170.
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.
243 x 965 x 946 x 781 = 173251002870
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.
243 : 1, 3, 9, 27, 81, 243
965 : 1, 5, 193, 965
946 : 1, 2, 11, 22, 43, 86, 473, 946
781 : 1, 11, 71, 781
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 243,965,946,781, is 1.
Now, the common factors can be found like this.
243:3x 3x 3x 3x 3
965:5x 193
946:2x 11x 43
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 = 173251002870/(1x11)
LCM = 173251002870/11
LCM = 15750091170
Thus, we can understand that the LCM of 243,965,946,781 is 15750091170.
