Given numbers are 505,564,155,387
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 505,564,155,387 is 1138995180.
Find LCM of 505,564,155,387 with Prime Factorization
| 3 | 505, 564, 155, 387 |
| 5 | 505, 188, 155, 129 |
| 101, 188, 31, 129 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 101 x 188 x 31 x 129 = 1138995180
Therefore, the lowest common multiple of 505,564,155,387 is 1138995180.
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.
505 x 564 x 155 x 387 = 17084927700
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.
505 : 1, 5, 101, 505
564 : 1, 2, 3, 4, 6, 12, 47, 94, 141, 188, 282, 564
155 : 1, 5, 31, 155
387 : 1, 3, 9, 43, 129, 387
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 505,564,155,387, is 1.
Now, the common factors can be found like this.
505:5x 101
564:2x 2x 3x 47
155:5x 31
387:3x 3x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5 = 15
Therefore, the value for common factors is 15.
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 = 17084927700/(1x15)
LCM = 17084927700/15
LCM = 1138995180
Thus, we can understand that the LCM of 505,564,155,387 is 1138995180.
