Given numbers are 741,572,465,942,989
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 741,572,465,942,989 is 784690738260.
Find LCM of 741,572,465,942,989 with Prime Factorization
| 2 | 741, 572, 465, 942, 989 |
| 3 | 741, 286, 465, 471, 989 |
| 13 | 247, 286, 155, 157, 989 |
| 19, 22, 155, 157, 989 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 19 x 22 x 155 x 157 x 989 = 784690738260
Therefore, the lowest common multiple of 741,572,465,942,989 is 784690738260.
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.
741 x 572 x 465 x 942 x 989 = 183617632752840
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.
741 : 1, 3, 13, 19, 39, 57, 247, 741
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
465 : 1, 3, 5, 15, 31, 93, 155, 465
942 : 1, 2, 3, 6, 157, 314, 471, 942
989 : 1, 23, 43, 989
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 741,572,465,942,989, is 1.
Now, the common factors can be found like this.
741:3x 13x 19
572:2x 2x 11x 13
465:3x 5x 31
942:2x 3x 157
989:23x 43
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 3x 13 = 234
Therefore, the value for common factors is 234.
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 = 183617632752840/(1x234)
LCM = 183617632752840/234
LCM = 784690738260
Thus, we can understand that the LCM of 741,572,465,942,989 is 784690738260.
