Find LCM of 318,180,972,660,457 with Prime Factorization
| 2 | 318, 180, 972, 660, 457 |
| 2 | 159, 90, 486, 330, 457 |
| 3 | 159, 45, 243, 165, 457 |
| 3 | 53, 15, 81, 55, 457 |
| 5 | 53, 5, 27, 55, 457 |
| 53, 1, 27, 11, 457 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 53 x 1 x 27 x 11 x 457 = 1294854660
Therefore, the lowest common multiple of 318,180,972,660,457 is 1294854660.
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.
318 x 180 x 972 x 660 x 457 = 16781316393600
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.
318 : 1, 2, 3, 6, 53, 106, 159, 318
180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
457 : 1, 457
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 318,180,972,660,457, is 1.
Now, the common factors can be found like this.
318:2x 3x 53
180:2x 2x 3x 3x 5
972:2x 2x 3x 3x 3x 3x 3
660:2x 2x 3x 5x 11
457:457
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 3x 3x 3x 3x 5 = 12960
Therefore, the value for common factors is 12960.
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 = 16781316393600/(1x12960)
LCM = 16781316393600/12960
LCM = 1294854660
Thus, we can understand that the LCM of 318,180,972,660,457 is 1294854660.
