Given numbers are 973,738,765,237,221
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 973,738,765,237,221 is 62684269830.
Find LCM of 973,738,765,237,221 with Prime Factorization
| 3 | 973, 738, 765, 237, 221 |
| 3 | 973, 246, 255, 79, 221 |
| 17 | 973, 82, 85, 79, 221 |
| 973, 82, 5, 79, 13 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 17 x 973 x 82 x 5 x 79 x 13 = 62684269830
Therefore, the lowest common multiple of 973,738,765,237,221 is 62684269830.
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.
973 x 738 x 765 x 237 x 221 = 28772079851970
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.
973 : 1, 7, 139, 973
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
237 : 1, 3, 79, 237
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 973,738,765,237,221, is 1.
Now, the common factors can be found like this.
973:7x 139
738:2x 3x 3x 41
765:3x 3x 5x 17
237:3x 79
221:13x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 17 = 459
Therefore, the value for common factors is 459.
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 = 28772079851970/(1x459)
LCM = 28772079851970/459
LCM = 62684269830
Thus, we can understand that the LCM of 973,738,765,237,221 is 62684269830.
