Given numbers are 380,843,989,297
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 380,843,989,297 is 31364809740.
Find LCM of 380,843,989,297 with Prime Factorization
| 3 | 380, 843, 989, 297 |
| 380, 281, 989, 99 |
Multiply the prime numbers at the bottom and the left side.
3 x 380 x 281 x 989 x 99 = 31364809740
Therefore, the lowest common multiple of 380,843,989,297 is 31364809740.
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.
380 x 843 x 989 x 297 = 94094429220
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.
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
843 : 1, 3, 281, 843
989 : 1, 23, 43, 989
297 : 1, 3, 9, 11, 27, 33, 99, 297
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 380,843,989,297, is 1.
Now, the common factors can be found like this.
380:2x 2x 5x 19
843:3x 281
989:23x 43
297:3x 3x 3x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 94094429220/(1x3)
LCM = 94094429220/3
LCM = 31364809740
Thus, we can understand that the LCM of 380,843,989,297 is 31364809740.
