Find LCM of 984,488,731,992,639 with Prime Factorization
| 2 | 984, 488, 731, 992, 639 |
| 2 | 492, 244, 731, 496, 639 |
| 2 | 246, 122, 731, 248, 639 |
| 3 | 123, 61, 731, 124, 639 |
| 41, 61, 731, 124, 213 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 41 x 61 x 731 x 124 x 213 = 1158893692128
Therefore, the lowest common multiple of 984,488,731,992,639 is 1158893692128.
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.
984 x 488 x 731 x 992 x 639 = 222507588888576
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.
984 : 1, 2, 3, 4, 6, 8, 12, 24, 41, 82, 123, 164, 246, 328, 492, 984
488 : 1, 2, 4, 8, 61, 122, 244, 488
731 : 1, 17, 43, 731
992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992
639 : 1, 3, 9, 71, 213, 639
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 984,488,731,992,639, is 1.
Now, the common factors can be found like this.
984:2x 2x 2x 3x 41
488:2x 2x 2x 61
731:17x 43
992:2x 2x 2x 2x 2x 31
639:3x 3x 71
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 2x 2x 2x 3 = 192
Therefore, the value for common factors is 192.
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 = 222507588888576/(1x192)
LCM = 222507588888576/192
LCM = 1158893692128
Thus, we can understand that the LCM of 984,488,731,992,639 is 1158893692128.
