The LCM of 180,930,308,721 is 44254980.
Find LCM of 180,930,308,721 with Prime Factorization
| 2 | 180, 930, 308, 721 |
| 2 | 90, 465, 154, 721 |
| 3 | 45, 465, 77, 721 |
| 5 | 15, 155, 77, 721 |
| 7 | 3, 31, 77, 721 |
| 3, 31, 11, 103 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 3 x 31 x 11 x 103 = 44254980
Therefore, the lowest common multiple of 180,930,308,721 is 44254980.
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.
180 x 930 x 308 x 721 = 37174183200
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.
180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
930 : 1, 2, 3, 5, 6, 10, 15, 30, 31, 62, 93, 155, 186, 310, 465, 930
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
721 : 1, 7, 103, 721
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 180,930,308,721, is 1.
Now, the common factors can be found like this.
180:2x 2x 3x 3x 5
930:2x 3x 5x 31
308:2x 2x 7x 11
721:7x 103
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 3x 5x 7 = 840
Therefore, the value for common factors is 840.
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 = 37174183200/(1x840)
LCM = 37174183200/840
LCM = 44254980
Thus, we can understand that the LCM of 180,930,308,721 is 44254980.
