Find LCM of 936,987,789,320,912 with Prime Factorization
| 2 | 936, 987, 789, 320, 912 |
| 2 | 468, 987, 789, 160, 456 |
| 2 | 234, 987, 789, 80, 228 |
| 2 | 117, 987, 789, 40, 114 |
| 3 | 117, 987, 789, 20, 57 |
| 39, 329, 263, 20, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 39 x 329 x 263 x 20 x 19 = 61551846720
Therefore, the lowest common multiple of 936,987,789,320,912 is 61551846720.
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.
936 x 987 x 789 x 320 x 912 = 212723182264320
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.
936 : 1, 2, 3, 4, 6, 8, 9, 12, 13, 18, 24, 26, 36, 39, 52, 72, 78, 104, 117, 156, 234, 312, 468, 936
987 : 1, 3, 7, 21, 47, 141, 329, 987
789 : 1, 3, 263, 789
320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 936,987,789,320,912, is 1.
Now, the common factors can be found like this.
936:2x 2x 2x 3x 3x 13
987:3x 7x 47
789:3x 263
320:2x 2x 2x 2x 2x 2x 5
912:2x 2x 2x 2x 3x 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 2x 2x 2x 2x 2x 2x 3x 3x 3 = 3456
Therefore, the value for common factors is 3456.
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 = 212723182264320/(1x3456)
LCM = 212723182264320/3456
LCM = 61551846720
Thus, we can understand that the LCM of 936,987,789,320,912 is 61551846720.
