Given numbers are 972,438,899,847,986
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 972,438,899,847,986 is 918504204156.
Find LCM of 972,438,899,847,986 with Prime Factorization
| 2 | 972, 438, 899, 847, 986 |
| 3 | 486, 219, 899, 847, 493 |
| 29 | 162, 73, 899, 847, 493 |
| 162, 73, 31, 847, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 29 x 162 x 73 x 31 x 847 x 17 = 918504204156
Therefore, the lowest common multiple of 972,438,899,847,986 is 918504204156.
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 438 x 899 x 847 x 986 = 319639463046288
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
438 : 1, 2, 3, 6, 73, 146, 219, 438
899 : 1, 29, 31, 899
847 : 1, 7, 11, 77, 121, 847
986 : 1, 2, 17, 29, 34, 58, 493, 986
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 972,438,899,847,986, is 1.
Now, the common factors can be found like this.
972:2x 2x 3x 3x 3x 3x 3
438:2x 3x 73
899:29x 31
847:7x 11x 11
986:2x 17x 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 2x 3x 29 = 348
Therefore, the value for common factors is 348.
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 = 319639463046288/(1x348)
LCM = 319639463046288/348
LCM = 918504204156
Thus, we can understand that the LCM of 972,438,899,847,986 is 918504204156.
