Given numbers are 510,661,390,906,922
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 510,661,390,906,922 is 305065334730.
Find LCM of 510,661,390,906,922 with Prime Factorization
| 2 | 510, 661, 390, 906, 922 |
| 3 | 255, 661, 195, 453, 461 |
| 5 | 85, 661, 65, 151, 461 |
| 17, 661, 13, 151, 461 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 17 x 661 x 13 x 151 x 461 = 305065334730
Therefore, the lowest common multiple of 510,661,390,906,922 is 305065334730.
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.
510 x 661 x 390 x 906 x 922 = 109823520502800
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.
510 : 1, 2, 3, 5, 6, 10, 15, 17, 30, 34, 51, 85, 102, 170, 255, 510
661 : 1, 661
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
906 : 1, 2, 3, 6, 151, 302, 453, 906
922 : 1, 2, 461, 922
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 510,661,390,906,922, is 1.
Now, the common factors can be found like this.
510:2x 3x 5x 17
661:661
390:2x 3x 5x 13
906:2x 3x 151
922:2x 461
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 3x 3x 5 = 360
Therefore, the value for common factors is 360.
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 = 109823520502800/(1x360)
LCM = 109823520502800/360
LCM = 305065334730
Thus, we can understand that the LCM of 510,661,390,906,922 is 305065334730.
