Find LCM of 504,249,868,420,515 with Prime Factorization
| 2 | 504, 249, 868, 420, 515 |
| 2 | 252, 249, 434, 210, 515 |
| 3 | 126, 249, 217, 105, 515 |
| 5 | 42, 83, 217, 35, 515 |
| 7 | 42, 83, 217, 7, 103 |
| 6, 83, 31, 1, 103 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 6 x 83 x 31 x 1 x 103 = 667847880
Therefore, the lowest common multiple of 504,249,868,420,515 is 667847880.
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 249 x 868 x 420 x 515 = 23561673206400
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
249 : 1, 3, 83, 249
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
515 : 1, 5, 103, 515
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 504,249,868,420,515, is 1.
Now, the common factors can be found like this.
504:2x 2x 2x 3x 3x 7
249:3x 83
868:2x 2x 7x 31
420:2x 2x 3x 5x 7
515:5x 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 2x 3x 3x 5x 7x 7 = 35280
Therefore, the value for common factors is 35280.
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 = 23561673206400/(1x35280)
LCM = 23561673206400/35280
LCM = 667847880
Thus, we can understand that the LCM of 504,249,868,420,515 is 667847880.
