Given numbers are 157,180,542,465
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 157,180,542,465 is 237412260.
Find LCM of 157,180,542,465 with Prime Factorization
| 2 | 157, 180, 542, 465 |
| 3 | 157, 90, 271, 465 |
| 5 | 157, 30, 271, 155 |
| 157, 6, 271, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 157 x 6 x 271 x 31 = 237412260
Therefore, the lowest common multiple of 157,180,542,465 is 237412260.
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.
157 x 180 x 542 x 465 = 7122367800
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.
157 : 1, 157
180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
542 : 1, 2, 271, 542
465 : 1, 3, 5, 15, 31, 93, 155, 465
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 157,180,542,465, is 1.
Now, the common factors can be found like this.
157:157
180:2x 2x 3x 3x 5
542:2x 271
465:3x 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 3x 5 = 30
Therefore, the value for common factors is 30.
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 = 7122367800/(1x30)
LCM = 7122367800/30
LCM = 237412260
Thus, we can understand that the LCM of 157,180,542,465 is 237412260.
