Given numbers are 902,776,455,660
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 902,776,455,660 is 477717240.
Find LCM of 902,776,455,660 with Prime Factorization
| 2 | 902, 776, 455, 660 |
| 2 | 451, 388, 455, 330 |
| 5 | 451, 194, 455, 165 |
| 11 | 451, 194, 91, 33 |
| 41, 194, 91, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 11 x 41 x 194 x 91 x 3 = 477717240
Therefore, the lowest common multiple of 902,776,455,660 is 477717240.
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.
902 x 776 x 455 x 660 = 210195585600
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.
902 : 1, 2, 11, 22, 41, 82, 451, 902
776 : 1, 2, 4, 8, 97, 194, 388, 776
455 : 1, 5, 7, 13, 35, 65, 91, 455
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 902,776,455,660, is 1.
Now, the common factors can be found like this.
902:2x 11x 41
776:2x 2x 2x 97
455:5x 7x 13
660:2x 2x 3x 5x 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 2x 2x 5x 11 = 440
Therefore, the value for common factors is 440.
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 = 210195585600/(1x440)
LCM = 210195585600/440
LCM = 477717240
Thus, we can understand that the LCM of 902,776,455,660 is 477717240.
