Given numbers are 638,203,497,797
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 638,203,497,797 is 252717542.
Find LCM of 638,203,497,797 with Prime Factorization
| 7 | 638, 203, 497, 797 |
| 29 | 638, 29, 71, 797 |
| 22, 1, 71, 797 |
Multiply the prime numbers at the bottom and the left side.
7 x 29 x 22 x 1 x 71 x 797 = 252717542
Therefore, the lowest common multiple of 638,203,497,797 is 252717542.
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.
638 x 203 x 497 x 797 = 51301661026
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.
638 : 1, 2, 11, 22, 29, 58, 319, 638
203 : 1, 7, 29, 203
497 : 1, 7, 71, 497
797 : 1, 797
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,203,497,797, is 1.
Now, the common factors can be found like this.
638:2x 11x 29
203:7x 29
497:7x 71
797:797
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 29 = 203
Therefore, the value for common factors is 203.
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 = 51301661026/(1x203)
LCM = 51301661026/203
LCM = 252717542
Thus, we can understand that the LCM of 638,203,497,797 is 252717542.
