Given numbers are 740,328,831,407,938
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 740,328,831,407,938 is 260142987720.
Find LCM of 740,328,831,407,938 with Prime Factorization
| 2 | 740, 328, 831, 407, 938 |
| 2 | 370, 164, 831, 407, 469 |
| 37 | 185, 82, 831, 407, 469 |
| 5, 82, 831, 11, 469 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 37 x 5 x 82 x 831 x 11 x 469 = 260142987720
Therefore, the lowest common multiple of 740,328,831,407,938 is 260142987720.
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.
740 x 328 x 831 x 407 x 938 = 77002324365120
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.
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
328 : 1, 2, 4, 8, 41, 82, 164, 328
831 : 1, 3, 277, 831
407 : 1, 11, 37, 407
938 : 1, 2, 7, 14, 67, 134, 469, 938
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 740,328,831,407,938, is 1.
Now, the common factors can be found like this.
740:2x 2x 5x 37
328:2x 2x 2x 41
831:3x 277
407:11x 37
938:2x 7x 67
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 37 = 296
Therefore, the value for common factors is 296.
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 = 77002324365120/(1x296)
LCM = 77002324365120/296
LCM = 260142987720
Thus, we can understand that the LCM of 740,328,831,407,938 is 260142987720.
