The LCM of 227,312,989,920 is 350224680.
Find LCM of 227,312,989,920 with Prime Factorization
| 2 | 227, 312, 989, 920 |
| 2 | 227, 156, 989, 460 |
| 2 | 227, 78, 989, 230 |
| 23 | 227, 39, 989, 115 |
| 227, 39, 43, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 23 x 227 x 39 x 43 x 5 = 350224680
Therefore, the lowest common multiple of 227,312,989,920 is 350224680.
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.
227 x 312 x 989 x 920 = 64441341120
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.
227 : 1, 227
312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312
989 : 1, 23, 43, 989
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 227,312,989,920, is 1.
Now, the common factors can be found like this.
227:227
312:2x 2x 2x 3x 13
989:23x 43
920:2x 2x 2x 5x 23
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 23 = 184
Therefore, the value for common factors is 184.
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 = 64441341120/(1x184)
LCM = 64441341120/184
LCM = 350224680
Thus, we can understand that the LCM of 227,312,989,920 is 350224680.
