Find LCM of 992,635,138,320 with Prime Factorization
| 2 | 992, 635, 138, 320 |
| 2 | 496, 635, 69, 160 |
| 2 | 248, 635, 69, 80 |
| 2 | 124, 635, 69, 40 |
| 2 | 62, 635, 69, 20 |
| 5 | 31, 635, 69, 10 |
| 31, 127, 69, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 5 x 31 x 127 x 69 x 2 = 86928960
Therefore, the lowest common multiple of 992,635,138,320 is 86928960.
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.
992 x 635 x 138 x 320 = 27817267200
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.
992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992
635 : 1, 5, 127, 635
138 : 1, 2, 3, 6, 23, 46, 69, 138
320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 992,635,138,320, is 1.
Now, the common factors can be found like this.
992:2x 2x 2x 2x 2x 31
635:5x 127
138:2x 3x 23
320:2x 2x 2x 2x 2x 2x 5
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 5 = 320
Therefore, the value for common factors is 320.
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 = 27817267200/(1x320)
LCM = 27817267200/320
LCM = 86928960
Thus, we can understand that the LCM of 992,635,138,320 is 86928960.
