Given numbers are 917,184,902,861
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 917,184,902,861 is 228288984.
Find LCM of 917,184,902,861 with Prime Factorization
| 2 | 917, 184, 902, 861 |
| 7 | 917, 92, 451, 861 |
| 41 | 131, 92, 451, 123 |
| 131, 92, 11, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 41 x 131 x 92 x 11 x 3 = 228288984
Therefore, the lowest common multiple of 917,184,902,861 is 228288984.
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.
917 x 184 x 902 x 861 = 131037876816
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.
917 : 1, 7, 131, 917
184 : 1, 2, 4, 8, 23, 46, 92, 184
902 : 1, 2, 11, 22, 41, 82, 451, 902
861 : 1, 3, 7, 21, 41, 123, 287, 861
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 917,184,902,861, is 1.
Now, the common factors can be found like this.
917:7x 131
184:2x 2x 2x 23
902:2x 11x 41
861:3x 7x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 41 = 574
Therefore, the value for common factors is 574.
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 = 131037876816/(1x574)
LCM = 131037876816/574
LCM = 228288984
Thus, we can understand that the LCM of 917,184,902,861 is 228288984.
