Find LCM of 756,321,120,294,792 with Prime Factorization
| 2 | 756, 321, 120, 294, 792 |
| 2 | 378, 321, 60, 147, 396 |
| 2 | 189, 321, 30, 147, 198 |
| 3 | 189, 321, 15, 147, 99 |
| 3 | 63, 107, 5, 49, 33 |
| 7 | 21, 107, 5, 49, 11 |
| 3, 107, 5, 7, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 7 x 3 x 107 x 5 x 7 x 11 = 62286840
Therefore, the lowest common multiple of 756,321,120,294,792 is 62286840.
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.
756 x 321 x 120 x 294 x 792 = 6780794549760
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.
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
321 : 1, 3, 107, 321
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
294 : 1, 2, 3, 6, 7, 14, 21, 42, 49, 98, 147, 294
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
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 756,321,120,294,792, is 3.
Now, the common factors can be found like this.
756:2x 2x 3x 3x 3x 7
321:3x 107
120:2x 2x 2x 3x 5
294:2x 3x 7x 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 3x 3x 3x 3x 7 = 36288
Therefore, the value for common factors is 36288.
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 = 6780794549760/(3x36288)
LCM = 6780794549760/108864
LCM = 62286840
Thus, we can understand that the LCM of 756,321,120,294,792 is 62286840.
