Given numbers are 188,688,623,756
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 188,688,623,756 is 543923856.
Find LCM of 188,688,623,756 with Prime Factorization
| 2 | 188, 688, 623, 756 |
| 2 | 94, 344, 623, 378 |
| 7 | 47, 172, 623, 189 |
| 47, 172, 89, 27 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 47 x 172 x 89 x 27 = 543923856
Therefore, the lowest common multiple of 188,688,623,756 is 543923856.
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 688 x 623 x 756 = 60919471872
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
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
623 : 1, 7, 89, 623
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 188,688,623,756, is 1.
Now, the common factors can be found like this.
188:2x 2x 47
688:2x 2x 2x 2x 43
623:7x 89
756:2x 2x 3x 3x 3x 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 7 = 112
Therefore, the value for common factors is 112.
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 = 60919471872/(1x112)
LCM = 60919471872/112
LCM = 543923856
Thus, we can understand that the LCM of 188,688,623,756 is 543923856.
