Given numbers are 505,938,871,754
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 505,938,871,754 is 178581130.
Find LCM of 505,938,871,754 with Prime Factorization
| 2 | 505, 938, 871, 754 |
| 13 | 505, 469, 871, 377 |
| 67 | 505, 469, 67, 29 |
| 505, 7, 1, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 67 x 505 x 7 x 1 x 29 = 178581130
Therefore, the lowest common multiple of 505,938,871,754 is 178581130.
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.
505 x 938 x 871 x 754 = 311088328460
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.
505 : 1, 5, 101, 505
938 : 1, 2, 7, 14, 67, 134, 469, 938
871 : 1, 13, 67, 871
754 : 1, 2, 13, 26, 29, 58, 377, 754
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 505,938,871,754, is 1.
Now, the common factors can be found like this.
505:5x 101
938:2x 7x 67
871:13x 67
754:2x 13x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 13x 67 = 1742
Therefore, the value for common factors is 1742.
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 = 311088328460/(1x1742)
LCM = 311088328460/1742
LCM = 178581130
Thus, we can understand that the LCM of 505,938,871,754 is 178581130.
