Given numbers are 265,981,770,242
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 265,981,770,242 is 440380710.
Find LCM of 265,981,770,242 with Prime Factorization
| 2 | 265, 981, 770, 242 |
| 5 | 265, 981, 385, 121 |
| 11 | 53, 981, 77, 121 |
| 53, 981, 7, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 53 x 981 x 7 x 11 = 440380710
Therefore, the lowest common multiple of 265,981,770,242 is 440380710.
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.
265 x 981 x 770 x 242 = 48441878100
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.
265 : 1, 5, 53, 265
981 : 1, 3, 9, 109, 327, 981
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
242 : 1, 2, 11, 22, 121, 242
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 265,981,770,242, is 1.
Now, the common factors can be found like this.
265:5x 53
981:3x 3x 109
770:2x 5x 7x 11
242:2x 11x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 11 = 110
Therefore, the value for common factors is 110.
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 = 48441878100/(1x110)
LCM = 48441878100/110
LCM = 440380710
Thus, we can understand that the LCM of 265,981,770,242 is 440380710.
