Given numbers are 188,188,762,840
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 188,188,762,840 is 5013960.
Find LCM of 188,188,762,840 with Prime Factorization
| 2 | 188, 188, 762, 840 |
| 2 | 94, 94, 381, 420 |
| 3 | 47, 47, 381, 210 |
| 47 | 47, 47, 127, 70 |
| 1, 1, 127, 70 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 47 x 1 x 1 x 127 x 70 = 5013960
Therefore, the lowest common multiple of 188,188,762,840 is 5013960.
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 188 x 762 x 840 = 22622987520
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
188 : 1, 2, 4, 47, 94, 188
762 : 1, 2, 3, 6, 127, 254, 381, 762
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 188,188,762,840, is 2.
Now, the common factors can be found like this.
188:2x 2x 47
188:2x 2x 47
762:2x 3x 127
840:2x 2x 2x 3x 5x 7
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 3x 47 = 2256
Therefore, the value for common factors is 2256.
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 = 22622987520/(2x2256)
LCM = 22622987520/4512
LCM = 5013960
Thus, we can understand that the LCM of 188,188,762,840 is 5013960.
