Find LCM of 188,817,903,972 with Prime Factorization
| 2 | 188, 817, 903, 972 |
| 2 | 94, 817, 903, 486 |
| 3 | 47, 817, 903, 243 |
| 43 | 47, 817, 301, 81 |
| 47, 19, 7, 81 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 43 x 47 x 19 x 7 x 81 = 261266796
Therefore, the lowest common multiple of 188,817,903,972 is 261266796.
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 817 x 903 x 972 = 134813666736
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
817 : 1, 19, 43, 817
903 : 1, 3, 7, 21, 43, 129, 301, 903
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 188,817,903,972, is 1.
Now, the common factors can be found like this.
188:2x 2x 47
817:19x 43
903:3x 7x 43
972:2x 2x 3x 3x 3x 3x 3
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 43 = 516
Therefore, the value for common factors is 516.
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 = 134813666736/(1x516)
LCM = 134813666736/516
LCM = 261266796
Thus, we can understand that the LCM of 188,817,903,972 is 261266796.
