Given numbers are 171,920,254,438,703
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 171,920,254,438,703 is 53965007640.
Find LCM of 171,920,254,438,703 with Prime Factorization
| 2 | 171, 920, 254, 438, 703 |
| 3 | 171, 460, 127, 219, 703 |
| 19 | 57, 460, 127, 73, 703 |
| 3, 460, 127, 73, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 3 x 460 x 127 x 73 x 37 = 53965007640
Therefore, the lowest common multiple of 171,920,254,438,703 is 53965007640.
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.
171 x 920 x 254 x 438 x 703 = 12304021741920
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.
171 : 1, 3, 9, 19, 57, 171
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
254 : 1, 2, 127, 254
438 : 1, 2, 3, 6, 73, 146, 219, 438
703 : 1, 19, 37, 703
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 171,920,254,438,703, is 1.
Now, the common factors can be found like this.
171:3x 3x 19
920:2x 2x 2x 5x 23
254:2x 127
438:2x 3x 73
703:19x 37
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 3x 19 = 228
Therefore, the value for common factors is 228.
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 = 12304021741920/(1x228)
LCM = 12304021741920/228
LCM = 53965007640
Thus, we can understand that the LCM of 171,920,254,438,703 is 53965007640.
