The LCM of 504,409,240,985 is 406087920.
Find LCM of 504,409,240,985 with Prime Factorization
| 2 | 504, 409, 240, 985 |
| 2 | 252, 409, 120, 985 |
| 2 | 126, 409, 60, 985 |
| 3 | 63, 409, 30, 985 |
| 5 | 21, 409, 10, 985 |
| 21, 409, 2, 197 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 21 x 409 x 2 x 197 = 406087920
Therefore, the lowest common multiple of 504,409,240,985 is 406087920.
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.
504 x 409 x 240 x 985 = 48730550400
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.
504 : 1, 2, 3, 4, 6, 7, 8, 9, 12, 14, 18, 21, 24, 28, 36, 42, 56, 63, 72, 84, 126, 168, 252, 504
409 : 1, 409
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
985 : 1, 5, 197, 985
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 504,409,240,985, is 1.
Now, the common factors can be found like this.
504:2x 2x 2x 3x 3x 7
409:409
240:2x 2x 2x 2x 3x 5
985:5x 197
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 5 = 120
Therefore, the value for common factors is 120.
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 = 48730550400/(1x120)
LCM = 48730550400/120
LCM = 406087920
Thus, we can understand that the LCM of 504,409,240,985 is 406087920.
