Given numbers are 762,289,385,254,998
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 762,289,385,254,998 is 42307181070.
Find LCM of 762,289,385,254,998 with Prime Factorization
| 2 | 762, 289, 385, 254, 998 |
| 127 | 381, 289, 385, 127, 499 |
| 3, 289, 385, 1, 499 |
Multiply the prime numbers at the bottom and the left side.
2 x 127 x 3 x 289 x 385 x 1 x 499 = 42307181070
Therefore, the lowest common multiple of 762,289,385,254,998 is 42307181070.
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.
762 x 289 x 385 x 254 x 998 = 21492047983560
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.
762 : 1, 2, 3, 6, 127, 254, 381, 762
289 : 1, 17, 289
385 : 1, 5, 7, 11, 35, 55, 77, 385
254 : 1, 2, 127, 254
998 : 1, 2, 499, 998
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 762,289,385,254,998, is 1.
Now, the common factors can be found like this.
762:2x 3x 127
289:17x 17
385:5x 7x 11
254:2x 127
998:2x 499
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 127 = 508
Therefore, the value for common factors is 508.
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 = 21492047983560/(1x508)
LCM = 21492047983560/508
LCM = 42307181070
Thus, we can understand that the LCM of 762,289,385,254,998 is 42307181070.
