Given numbers are 187,720,595,643,106
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 187,720,595,643,106 is 32118775920.
Find LCM of 187,720,595,643,106 with Prime Factorization
| 2 | 187, 720, 595, 643, 106 |
| 5 | 187, 360, 595, 643, 53 |
| 17 | 187, 72, 119, 643, 53 |
| 11, 72, 7, 643, 53 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 17 x 11 x 72 x 7 x 643 x 53 = 32118775920
Therefore, the lowest common multiple of 187,720,595,643,106 is 32118775920.
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.
187 x 720 x 595 x 643 x 106 = 5460191906400
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.
187 : 1, 11, 17, 187
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
595 : 1, 5, 7, 17, 35, 85, 119, 595
643 : 1, 643
106 : 1, 2, 53, 106
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 187,720,595,643,106, is 1.
Now, the common factors can be found like this.
187:11x 17
720:2x 2x 2x 2x 3x 3x 5
595:5x 7x 17
643:643
106:2x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 17 = 170
Therefore, the value for common factors is 170.
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 = 5460191906400/(1x170)
LCM = 5460191906400/170
LCM = 32118775920
Thus, we can understand that the LCM of 187,720,595,643,106 is 32118775920.
