Given numbers are 854,868,972,775
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 854,868,972,775 is 321659100.
Find LCM of 854,868,972,775 with Prime Factorization
| 2 | 854, 868, 972, 775 |
| 2 | 427, 434, 486, 775 |
| 7 | 427, 217, 243, 775 |
| 31 | 61, 31, 243, 775 |
| 61, 1, 243, 25 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 31 x 61 x 1 x 243 x 25 = 321659100
Therefore, the lowest common multiple of 854,868,972,775 is 321659100.
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.
854 x 868 x 972 x 775 = 558400197600
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.
854 : 1, 2, 7, 14, 61, 122, 427, 854
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
775 : 1, 5, 25, 31, 155, 775
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 854,868,972,775, is 1.
Now, the common factors can be found like this.
854:2x 7x 61
868:2x 2x 7x 31
972:2x 2x 3x 3x 3x 3x 3
775:5x 5x 31
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 2x 7x 31 = 1736
Therefore, the value for common factors is 1736.
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 = 558400197600/(1x1736)
LCM = 558400197600/1736
LCM = 321659100
Thus, we can understand that the LCM of 854,868,972,775 is 321659100.
