Find LCM of 939,240,912,770 with Prime Factorization
| 2 | 939, 240, 912, 770 |
| 2 | 939, 120, 456, 385 |
| 2 | 939, 60, 228, 385 |
| 2 | 939, 30, 114, 385 |
| 3 | 939, 15, 57, 385 |
| 5 | 313, 5, 19, 385 |
| 313, 1, 19, 77 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 5 x 313 x 1 x 19 x 77 = 109900560
Therefore, the lowest common multiple of 939,240,912,770 is 109900560.
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.
939 x 240 x 912 x 770 = 158256806400
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.
939 : 1, 3, 313, 939
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 939,240,912,770, is 1.
Now, the common factors can be found like this.
939:3x 313
240:2x 2x 2x 2x 3x 5
912:2x 2x 2x 2x 3x 19
770:2x 5x 7x 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 3x 3x 5 = 1440
Therefore, the value for common factors is 1440.
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 = 158256806400/(1x1440)
LCM = 158256806400/1440
LCM = 109900560
Thus, we can understand that the LCM of 939,240,912,770 is 109900560.
