Given numbers are 972,494,624,993
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 972,494,624,993 is 317871216.
Find LCM of 972,494,624,993 with Prime Factorization
| 2 | 972, 494, 624, 993 |
| 2 | 486, 247, 312, 993 |
| 3 | 243, 247, 156, 993 |
| 13 | 81, 247, 52, 331 |
| 81, 19, 4, 331 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 13 x 81 x 19 x 4 x 331 = 317871216
Therefore, the lowest common multiple of 972,494,624,993 is 317871216.
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 494 x 624 x 993 = 297527458176
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
494 : 1, 2, 13, 19, 26, 38, 247, 494
624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624
993 : 1, 3, 331, 993
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 972,494,624,993, is 1.
Now, the common factors can be found like this.
972:2x 2x 3x 3x 3x 3x 3
494:2x 13x 19
624:2x 2x 2x 2x 3x 13
993:3x 331
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 3x 3x 13 = 936
Therefore, the value for common factors is 936.
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 = 297527458176/(1x936)
LCM = 297527458176/936
LCM = 317871216
Thus, we can understand that the LCM of 972,494,624,993 is 317871216.
