Find LCM of 784,364,923,338,761 with Prime Factorization
| 2 | 784, 364, 923, 338, 761 |
| 2 | 392, 182, 923, 169, 761 |
| 7 | 196, 91, 923, 169, 761 |
| 13 | 28, 13, 923, 169, 761 |
| 28, 1, 71, 13, 761 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 13 x 28 x 1 x 71 x 13 x 761 = 7158891376
Therefore, the lowest common multiple of 784,364,923,338,761 is 7158891376.
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.
784 x 364 x 923 x 338 x 761 = 67751747982464
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.
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
364 : 1, 2, 4, 7, 13, 14, 26, 28, 52, 91, 182, 364
923 : 1, 13, 71, 923
338 : 1, 2, 13, 26, 169, 338
761 : 1, 761
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 784,364,923,338,761, is 1.
Now, the common factors can be found like this.
784:2x 2x 2x 2x 7x 7
364:2x 2x 7x 13
923:13x 71
338:2x 13x 13
761:761
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 7x 13x 13 = 9464
Therefore, the value for common factors is 9464.
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 = 67751747982464/(1x9464)
LCM = 67751747982464/9464
LCM = 7158891376
Thus, we can understand that the LCM of 784,364,923,338,761 is 7158891376.
