Given numbers are 972,742,461,909
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 972,742,461,909 is 16790455332.
Find LCM of 972,742,461,909 with Prime Factorization
| 2 | 972, 742, 461, 909 |
| 3 | 486, 371, 461, 909 |
| 3 | 162, 371, 461, 303 |
| 54, 371, 461, 101 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 54 x 371 x 461 x 101 = 16790455332
Therefore, the lowest common multiple of 972,742,461,909 is 16790455332.
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 742 x 461 x 909 = 302228195976
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
742 : 1, 2, 7, 14, 53, 106, 371, 742
461 : 1, 461
909 : 1, 3, 9, 101, 303, 909
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 972,742,461,909, is 1.
Now, the common factors can be found like this.
972:2x 2x 3x 3x 3x 3x 3
742:2x 7x 53
461:461
909:3x 3x 101
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3 = 18
Therefore, the value for common factors is 18.
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 = 302228195976/(1x18)
LCM = 302228195976/18
LCM = 16790455332
Thus, we can understand that the LCM of 972,742,461,909 is 16790455332.
