Find LCM of 293,978,168,419,784 with Prime Factorization
| 2 | 293, 978, 168, 419, 784 |
| 2 | 293, 489, 84, 419, 392 |
| 2 | 293, 489, 42, 419, 196 |
| 3 | 293, 489, 21, 419, 98 |
| 7 | 293, 163, 7, 419, 98 |
| 293, 163, 1, 419, 14 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 293 x 163 x 1 x 419 x 14 = 47065921392
Therefore, the lowest common multiple of 293,978,168,419,784 is 47065921392.
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.
293 x 978 x 168 x 419 x 784 = 15814149587712
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.
293 : 1, 293
978 : 1, 2, 3, 6, 163, 326, 489, 978
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
419 : 1, 419
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 293,978,168,419,784, is 1.
Now, the common factors can be found like this.
293:293
978:2x 3x 163
168:2x 2x 2x 3x 7
419:419
784:2x 2x 2x 2x 7x 7
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 3x 7 = 336
Therefore, the value for common factors is 336.
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 = 15814149587712/(1x336)
LCM = 15814149587712/336
LCM = 47065921392
Thus, we can understand that the LCM of 293,978,168,419,784 is 47065921392.
