Given numbers are 924,691,940,973
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 924,691,940,973 is 20856079860.
Find LCM of 924,691,940,973 with Prime Factorization
| 2 | 924, 691, 940, 973 |
| 2 | 462, 691, 470, 973 |
| 7 | 231, 691, 235, 973 |
| 33, 691, 235, 139 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 33 x 691 x 235 x 139 = 20856079860
Therefore, the lowest common multiple of 924,691,940,973 is 20856079860.
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.
924 x 691 x 940 x 973 = 583970236080
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.
924 : 1, 2, 3, 4, 6, 7, 11, 12, 14, 21, 22, 28, 33, 42, 44, 66, 77, 84, 132, 154, 231, 308, 462, 924
691 : 1, 691
940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940
973 : 1, 7, 139, 973
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 924,691,940,973, is 1.
Now, the common factors can be found like this.
924:2x 2x 3x 7x 11
691:691
940:2x 2x 5x 47
973:7x 139
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 7 = 28
Therefore, the value for common factors is 28.
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 = 583970236080/(1x28)
LCM = 583970236080/28
LCM = 20856079860
Thus, we can understand that the LCM of 924,691,940,973 is 20856079860.
