Given numbers are 638,930,757,775,452
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 638,930,757,775,452 is 253774484700.
Find LCM of 638,930,757,775,452 with Prime Factorization
| 2 | 638, 930, 757, 775, 452 |
| 5 | 319, 465, 757, 775, 226 |
| 31 | 319, 93, 757, 155, 226 |
| 319, 3, 757, 5, 226 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 31 x 319 x 3 x 757 x 5 x 226 = 253774484700
Therefore, the lowest common multiple of 638,930,757,775,452 is 253774484700.
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 930 x 757 x 775 x 452 = 157340180514000
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
930 : 1, 2, 3, 5, 6, 10, 15, 30, 31, 62, 93, 155, 186, 310, 465, 930
757 : 1, 757
775 : 1, 5, 25, 31, 155, 775
452 : 1, 2, 4, 113, 226, 452
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,930,757,775,452, is 1.
Now, the common factors can be found like this.
638:2x 11x 29
930:2x 3x 5x 31
757:757
775:5x 5x 31
452:2x 2x 113
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 5x 31 = 620
Therefore, the value for common factors is 620.
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 = 157340180514000/(1x620)
LCM = 157340180514000/620
LCM = 253774484700
Thus, we can understand that the LCM of 638,930,757,775,452 is 253774484700.
