Find LCM of 765,784,363,484 with Prime Factorization
| 2 | 765, 784, 363, 484 |
| 2 | 765, 392, 363, 242 |
| 3 | 765, 196, 363, 121 |
| 11 | 255, 196, 121, 121 |
| 11 | 255, 196, 11, 11 |
| 255, 196, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 11 x 255 x 196 x 1 x 1 = 72570960
Therefore, the lowest common multiple of 765,784,363,484 is 72570960.
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.
765 x 784 x 363 x 484 = 105373033920
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.
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
363 : 1, 3, 11, 33, 121, 363
484 : 1, 2, 4, 11, 22, 44, 121, 242, 484
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 765,784,363,484, is 1.
Now, the common factors can be found like this.
765:3x 3x 5x 17
784:2x 2x 2x 2x 7x 7
363:3x 11x 11
484:2x 2x 11x 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 3x 11x 11 = 1452
Therefore, the value for common factors is 1452.
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 = 105373033920/(1x1452)
LCM = 105373033920/1452
LCM = 72570960
Thus, we can understand that the LCM of 765,784,363,484 is 72570960.
