Given numbers are 838,777,989,382
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 838,777,989,382 is 122997050274.
Find LCM of 838,777,989,382 with Prime Factorization
| 2 | 838, 777, 989, 382 |
| 419, 777, 989, 191 |
Multiply the prime numbers at the bottom and the left side.
2 x 419 x 777 x 989 x 191 = 122997050274
Therefore, the lowest common multiple of 838,777,989,382 is 122997050274.
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.
838 x 777 x 989 x 382 = 245994100548
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.
838 : 1, 2, 419, 838
777 : 1, 3, 7, 21, 37, 111, 259, 777
989 : 1, 23, 43, 989
382 : 1, 2, 191, 382
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 838,777,989,382, is 1.
Now, the common factors can be found like this.
838:2x 419
777:3x 7x 37
989:23x 43
382:2x 191
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 245994100548/(1x2)
LCM = 245994100548/2
LCM = 122997050274
Thus, we can understand that the LCM of 838,777,989,382 is 122997050274.
