The LCM of 494,399,375,438,981 is 30954719250.
Find LCM of 494,399,375,438,981 with Prime Factorization
| 2 | 494, 399, 375, 438, 981 |
| 3 | 247, 399, 375, 219, 981 |
| 19 | 247, 133, 125, 73, 327 |
| 13, 7, 125, 73, 327 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 13 x 7 x 125 x 73 x 327 = 30954719250
Therefore, the lowest common multiple of 494,399,375,438,981 is 30954719250.
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.
494 x 399 x 375 x 438 x 981 = 31759541950500
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.
494 : 1, 2, 13, 19, 26, 38, 247, 494
399 : 1, 3, 7, 19, 21, 57, 133, 399
375 : 1, 3, 5, 15, 25, 75, 125, 375
438 : 1, 2, 3, 6, 73, 146, 219, 438
981 : 1, 3, 9, 109, 327, 981
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 494,399,375,438,981, is 1.
Now, the common factors can be found like this.
494:2x 13x 19
399:3x 7x 19
375:3x 5x 5x 5
438:2x 3x 73
981:3x 3x 109
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 19 = 1026
Therefore, the value for common factors is 1026.
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 = 31759541950500/(1x1026)
LCM = 31759541950500/1026
LCM = 30954719250
Thus, we can understand that the LCM of 494,399,375,438,981 is 30954719250.
