Find LCM of 972,216,189,318,328 with Prime Factorization
| 2 | 972, 216, 189, 318, 328 |
| 2 | 486, 108, 189, 159, 164 |
| 2 | 243, 54, 189, 159, 82 |
| 3 | 243, 27, 189, 159, 41 |
| 3 | 81, 9, 63, 53, 41 |
| 3 | 27, 3, 21, 53, 41 |
| 9, 1, 7, 53, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 3 x 9 x 1 x 7 x 53 x 41 = 29570184
Therefore, the lowest common multiple of 972,216,189,318,328 is 29570184.
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.
972 x 216 x 189 x 318 x 328 = 4138879514112
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.
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
216 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 108, 216
189 : 1, 3, 7, 9, 21, 27, 63, 189
318 : 1, 2, 3, 6, 53, 106, 159, 318
328 : 1, 2, 4, 8, 41, 82, 164, 328
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 972,216,189,318,328, is 1.
Now, the common factors can be found like this.
972:2x 2x 3x 3x 3x 3x 3
216:2x 2x 2x 3x 3x 3
189:3x 3x 3x 7
318:2x 3x 53
328:2x 2x 2x 41
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 2x 2x 3x 3x 3x 3x 3x 3x 3 = 139968
Therefore, the value for common factors is 139968.
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 = 4138879514112/(1x139968)
LCM = 4138879514112/139968
LCM = 29570184
Thus, we can understand that the LCM of 972,216,189,318,328 is 29570184.
