Given numbers are 942,516,871,938
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 942,516,871,938 is 493930164.
Find LCM of 942,516,871,938 with Prime Factorization
2 | 942, 516, 871, 938 |
3 | 471, 258, 871, 469 |
67 | 157, 86, 871, 469 |
157, 86, 13, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 67 x 157 x 86 x 13 x 7 = 493930164
Therefore, the lowest common multiple of 942,516,871,938 is 493930164.
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.
942 x 516 x 871 x 938 = 397119851856
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.
942 : 1, 2, 3, 6, 157, 314, 471, 942
516 : 1, 2, 3, 4, 6, 12, 43, 86, 129, 172, 258, 516
871 : 1, 13, 67, 871
938 : 1, 2, 7, 14, 67, 134, 469, 938
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 942,516,871,938, is 1.
Now, the common factors can be found like this.
942:2x 3x 157
516:2x 2x 3x 43
871:13x 67
938:2x 7x 67
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 67 = 804
Therefore, the value for common factors is 804.
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 = 397119851856/(1x804)
LCM = 397119851856/804
LCM = 493930164
Thus, we can understand that the LCM of 942,516,871,938 is 493930164.
