Given numbers are 398,497,796,740,775
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 398,497,796,740,775 is 11344174100.
Find LCM of 398,497,796,740,775 with Prime Factorization
| 2 | 398, 497, 796, 740, 775 |
| 2 | 199, 497, 398, 370, 775 |
| 5 | 199, 497, 199, 185, 775 |
| 199 | 199, 497, 199, 37, 155 |
| 1, 497, 1, 37, 155 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 199 x 1 x 497 x 1 x 37 x 155 = 11344174100
Therefore, the lowest common multiple of 398,497,796,740,775 is 11344174100.
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.
398 x 497 x 796 x 740 x 775 = 90299625836000
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.
398 : 1, 2, 199, 398
497 : 1, 7, 71, 497
796 : 1, 2, 4, 199, 398, 796
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
775 : 1, 5, 25, 31, 155, 775
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,497,796,740,775, is 1.
Now, the common factors can be found like this.
398:2x 199
497:7x 71
796:2x 2x 199
740:2x 2x 5x 37
775:5x 5x 31
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 2x 5x 199 = 7960
Therefore, the value for common factors is 7960.
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 = 90299625836000/(1x7960)
LCM = 90299625836000/7960
LCM = 11344174100
Thus, we can understand that the LCM of 398,497,796,740,775 is 11344174100.
