Given numbers are 188,680,720,629
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 188,680,720,629 is 21285360.
Find LCM of 188,680,720,629 with Prime Factorization
| 2 | 188, 680, 720, 629 |
| 2 | 94, 340, 360, 629 |
| 2 | 47, 170, 180, 629 |
| 5 | 47, 85, 90, 629 |
| 17 | 47, 17, 18, 629 |
| 47, 1, 18, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 17 x 47 x 1 x 18 x 37 = 21285360
Therefore, the lowest common multiple of 188,680,720,629 is 21285360.
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.
188 x 680 x 720 x 629 = 57896179200
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.
188 : 1, 2, 4, 47, 94, 188
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
629 : 1, 17, 37, 629
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 188,680,720,629, is 1.
Now, the common factors can be found like this.
188:2x 2x 47
680:2x 2x 2x 5x 17
720:2x 2x 2x 2x 3x 3x 5
629:17x 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 2x 2x 2x 5x 17 = 2720
Therefore, the value for common factors is 2720.
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 = 57896179200/(1x2720)
LCM = 57896179200/2720
LCM = 21285360
Thus, we can understand that the LCM of 188,680,720,629 is 21285360.
