Given numbers are 401,568,572,120
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 401,568,572,120 is 488562360.
Find LCM of 401,568,572,120 with Prime Factorization
| 2 | 401, 568, 572, 120 |
| 2 | 401, 284, 286, 60 |
| 2 | 401, 142, 143, 30 |
| 401, 71, 143, 15 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 401 x 71 x 143 x 15 = 488562360
Therefore, the lowest common multiple of 401,568,572,120 is 488562360.
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.
401 x 568 x 572 x 120 = 15633995520
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.
401 : 1, 401
568 : 1, 2, 4, 8, 71, 142, 284, 568
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 401,568,572,120, is 1.
Now, the common factors can be found like this.
401:401
568:2x 2x 2x 71
572:2x 2x 11x 13
120:2x 2x 2x 3x 5
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 2 = 32
Therefore, the value for common factors is 32.
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 = 15633995520/(1x32)
LCM = 15633995520/32
LCM = 488562360
Thus, we can understand that the LCM of 401,568,572,120 is 488562360.
