Given numbers are 507,160,831,356
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 507,160,831,356 is 1999851360.
Find LCM of 507,160,831,356 with Prime Factorization
| 2 | 507, 160, 831, 356 |
| 2 | 507, 80, 831, 178 |
| 3 | 507, 40, 831, 89 |
| 169, 40, 277, 89 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 169 x 40 x 277 x 89 = 1999851360
Therefore, the lowest common multiple of 507,160,831,356 is 1999851360.
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.
507 x 160 x 831 x 356 = 23998216320
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.
507 : 1, 3, 13, 39, 169, 507
160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160
831 : 1, 3, 277, 831
356 : 1, 2, 4, 89, 178, 356
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 507,160,831,356, is 1.
Now, the common factors can be found like this.
507:3x 13x 13
160:2x 2x 2x 2x 2x 5
831:3x 277
356:2x 2x 89
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 3 = 12
Therefore, the value for common factors is 12.
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 = 23998216320/(1x12)
LCM = 23998216320/12
LCM = 1999851360
Thus, we can understand that the LCM of 507,160,831,356 is 1999851360.
