The LCM of 240,121,242,157,824 is 469605840.
Find LCM of 240,121,242,157,824 with Prime Factorization
| 2 | 240, 121, 242, 157, 824 |
| 2 | 120, 121, 121, 157, 412 |
| 2 | 60, 121, 121, 157, 206 |
| 11 | 30, 121, 121, 157, 103 |
| 11 | 30, 11, 11, 157, 103 |
| 30, 1, 1, 157, 103 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 11 x 11 x 30 x 1 x 1 x 157 x 103 = 469605840
Therefore, the lowest common multiple of 240,121,242,157,824 is 469605840.
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.
240 x 121 x 242 x 157 x 824 = 909156906240
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.
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
121 : 1, 11, 121
242 : 1, 2, 11, 22, 121, 242
157 : 1, 157
824 : 1, 2, 4, 8, 103, 206, 412, 824
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 240,121,242,157,824, is 1.
Now, the common factors can be found like this.
240:2x 2x 2x 2x 3x 5
121:11x 11
242:2x 11x 11
157:157
824:2x 2x 2x 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 11x 11 = 1936
Therefore, the value for common factors is 1936.
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 = 909156906240/(1x1936)
LCM = 909156906240/1936
LCM = 469605840
Thus, we can understand that the LCM of 240,121,242,157,824 is 469605840.
