Find LCM of 984,639,928,168,792 with Prime Factorization
| 2 | 984, 639, 928, 168, 792 |
| 2 | 492, 639, 464, 84, 396 |
| 2 | 246, 639, 232, 42, 198 |
| 3 | 123, 639, 116, 21, 99 |
| 3 | 41, 213, 116, 7, 33 |
| 41, 71, 116, 7, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 41 x 71 x 116 x 7 x 11 = 1872075744
Therefore, the lowest common multiple of 984,639,928,168,792 is 1872075744.
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 639 x 928 x 168 x 792 = 77638725255168
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
639 : 1, 3, 9, 71, 213, 639
928 : 1, 2, 4, 8, 16, 29, 32, 58, 116, 232, 464, 928
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
792 : 1, 2, 3, 4, 6, 8, 9, 11, 12, 18, 22, 24, 33, 36, 44, 66, 72, 88, 99, 132, 198, 264, 396, 792
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 984,639,928,168,792, is 1.
Now, the common factors can be found like this.
984:2x 2x 2x 3x 41
639:3x 3x 71
928:2x 2x 2x 2x 2x 29
168:2x 2x 2x 3x 7
792:2x 2x 2x 3x 3x 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 2x 2x 2x 2x 2x 2x 3x 3x 3x 3 = 41472
Therefore, the value for common factors is 41472.
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 = 77638725255168/(1x41472)
LCM = 77638725255168/41472
LCM = 1872075744
Thus, we can understand that the LCM of 984,639,928,168,792 is 1872075744.
