Find LCM of 798,939,731,242,931 with Prime Factorization
2 | 798, 939, 731, 242, 931 |
3 | 399, 939, 731, 121, 931 |
7 | 133, 313, 731, 121, 931 |
19 | 19, 313, 731, 121, 133 |
1, 313, 731, 121, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 19 x 1 x 313 x 731 x 121 x 7 = 154649320518
Therefore, the lowest common multiple of 798,939,731,242,931 is 154649320518.
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.
798 x 939 x 731 x 242 x 931 = 123410157773364
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.
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
939 : 1, 3, 313, 939
731 : 1, 17, 43, 731
242 : 1, 2, 11, 22, 121, 242
931 : 1, 7, 19, 49, 133, 931
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 798,939,731,242,931, is 1.
Now, the common factors can be found like this.
798:2x 3x 7x 19
939:3x 313
731:17x 43
242:2x 11x 11
931:7x 7x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 7x 19 = 798
Therefore, the value for common factors is 798.
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 = 123410157773364/(1x798)
LCM = 123410157773364/798
LCM = 154649320518
Thus, we can understand that the LCM of 798,939,731,242,931 is 154649320518.
