Given numbers are 754,777,497,455
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 754,777,497,455 is 207979590.
Find LCM of 754,777,497,455 with Prime Factorization
| 7 | 754, 777, 497, 455 |
| 13 | 754, 111, 71, 65 |
| 58, 111, 71, 5 |
Multiply the prime numbers at the bottom and the left side.
7 x 13 x 58 x 111 x 71 x 5 = 207979590
Therefore, the lowest common multiple of 754,777,497,455 is 207979590.
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.
754 x 777 x 497 x 455 = 132482998830
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.
754 : 1, 2, 13, 26, 29, 58, 377, 754
777 : 1, 3, 7, 21, 37, 111, 259, 777
497 : 1, 7, 71, 497
455 : 1, 5, 7, 13, 35, 65, 91, 455
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 754,777,497,455, is 1.
Now, the common factors can be found like this.
754:2x 13x 29
777:3x 7x 37
497:7x 71
455:5x 7x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 7x 13 = 637
Therefore, the value for common factors is 637.
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 = 132482998830/(1x637)
LCM = 132482998830/637
LCM = 207979590
Thus, we can understand that the LCM of 754,777,497,455 is 207979590.
