The LCM of 520,400,620,505,949 is 1188527600.
Find LCM of 520,400,620,505,949 with Prime Factorization
| 2 | 520, 400, 620, 505, 949 |
| 2 | 260, 200, 310, 505, 949 |
| 2 | 130, 100, 155, 505, 949 |
| 5 | 65, 50, 155, 505, 949 |
| 13 | 13, 10, 31, 101, 949 |
| 1, 10, 31, 101, 73 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 13 x 1 x 10 x 31 x 101 x 73 = 1188527600
Therefore, the lowest common multiple of 520,400,620,505,949 is 1188527600.
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.
520 x 400 x 620 x 505 x 949 = 61803435200000
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.
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
505 : 1, 5, 101, 505
949 : 1, 13, 73, 949
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 520,400,620,505,949, is 1.
Now, the common factors can be found like this.
520:2x 2x 2x 5x 13
400:2x 2x 2x 2x 5x 5
620:2x 2x 5x 31
505:5x 101
949:13x 73
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 5x 5x 5x 13 = 52000
Therefore, the value for common factors is 52000.
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 = 61803435200000/(1x52000)
LCM = 61803435200000/52000
LCM = 1188527600
Thus, we can understand that the LCM of 520,400,620,505,949 is 1188527600.
