Given numbers are 157,942,471,495
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 157,942,471,495 is 155430.
Find LCM of 157,942,471,495 with Prime Factorization
| 3 | 157, 942, 471, 495 |
| 157 | 157, 314, 157, 165 |
| 1, 2, 1, 165 |
Multiply the prime numbers at the bottom and the left side.
3 x 157 x 1 x 2 x 1 x 165 = 155430
Therefore, the lowest common multiple of 157,942,471,495 is 155430.
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 942 x 471 x 495 = 34480746630
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
942 : 1, 2, 3, 6, 157, 314, 471, 942
471 : 1, 3, 157, 471
495 : 1, 3, 5, 9, 11, 15, 33, 45, 55, 99, 165, 495
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 157,942,471,495, is 1.
Now, the common factors can be found like this.
157:157
942:2x 3x 157
471:3x 157
495:3x 3x 5x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 157x 157 = 221841
Therefore, the value for common factors is 221841.
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 = 34480746630/(1x221841)
LCM = 34480746630/221841
LCM = 155430
Thus, we can understand that the LCM of 157,942,471,495 is 155430.
