Given numbers are 291,973,266,388
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 291,973,266,388 is 21518868.
Find LCM of 291,973,266,388 with Prime Factorization
| 2 | 291, 973, 266, 388 |
| 7 | 291, 973, 133, 194 |
| 97 | 291, 139, 19, 194 |
| 3, 139, 19, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 97 x 3 x 139 x 19 x 2 = 21518868
Therefore, the lowest common multiple of 291,973,266,388 is 21518868.
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.
291 x 973 x 266 x 388 = 29222622744
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.
291 : 1, 3, 97, 291
973 : 1, 7, 139, 973
266 : 1, 2, 7, 14, 19, 38, 133, 266
388 : 1, 2, 4, 97, 194, 388
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 291,973,266,388, is 1.
Now, the common factors can be found like this.
291:3x 97
973:7x 139
266:2x 7x 19
388:2x 2x 97
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 97 = 1358
Therefore, the value for common factors is 1358.
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 = 29222622744/(1x1358)
LCM = 29222622744/1358
LCM = 21518868
Thus, we can understand that the LCM of 291,973,266,388 is 21518868.
