Given numbers are 972,871,303,505
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 972,871,303,505 is 427539060.
Find LCM of 972,871,303,505 with Prime Factorization
| 3 | 972, 871, 303, 505 |
| 101 | 324, 871, 101, 505 |
| 324, 871, 1, 5 |
Multiply the prime numbers at the bottom and the left side.
3 x 101 x 324 x 871 x 1 x 5 = 427539060
Therefore, the lowest common multiple of 972,871,303,505 is 427539060.
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.
972 x 871 x 303 x 505 = 129544335180
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.
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
871 : 1, 13, 67, 871
303 : 1, 3, 101, 303
505 : 1, 5, 101, 505
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 972,871,303,505, is 1.
Now, the common factors can be found like this.
972:2x 2x 3x 3x 3x 3x 3
871:13x 67
303:3x 101
505:5x 101
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 101 = 303
Therefore, the value for common factors is 303.
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 = 129544335180/(1x303)
LCM = 129544335180/303
LCM = 427539060
Thus, we can understand that the LCM of 972,871,303,505 is 427539060.
