Given numbers are 262,847,245,428,390
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 262,847,245,428,390 is 64823298540.
Find LCM of 262,847,245,428,390 with Prime Factorization
| 2 | 262, 847, 245, 428, 390 |
| 5 | 131, 847, 245, 214, 195 |
| 7 | 131, 847, 49, 214, 39 |
| 131, 121, 7, 214, 39 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 131 x 121 x 7 x 214 x 39 = 64823298540
Therefore, the lowest common multiple of 262,847,245,428,390 is 64823298540.
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.
262 x 847 x 245 x 428 x 390 = 9075261795600
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.
262 : 1, 2, 131, 262
847 : 1, 7, 11, 77, 121, 847
245 : 1, 5, 7, 35, 49, 245
428 : 1, 2, 4, 107, 214, 428
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 262,847,245,428,390, is 1.
Now, the common factors can be found like this.
262:2x 131
847:7x 11x 11
245:5x 7x 7
428:2x 2x 107
390:2x 3x 5x 13
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 5x 7 = 140
Therefore, the value for common factors is 140.
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 = 9075261795600/(1x140)
LCM = 9075261795600/140
LCM = 64823298540
Thus, we can understand that the LCM of 262,847,245,428,390 is 64823298540.
