Find LCM of 392,987,980,496,725 with Prime Factorization
| 2 | 392, 987, 980, 496, 725 |
| 2 | 196, 987, 490, 248, 725 |
| 2 | 98, 987, 245, 124, 725 |
| 5 | 49, 987, 245, 62, 725 |
| 7 | 49, 987, 49, 62, 145 |
| 7 | 7, 141, 7, 62, 145 |
| 1, 141, 1, 62, 145 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 7 x 7 x 1 x 141 x 1 x 62 x 145 = 2484476400
Therefore, the lowest common multiple of 392,987,980,496,725 is 2484476400.
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.
392 x 987 x 980 x 496 x 725 = 136348064832000
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.
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
987 : 1, 3, 7, 21, 47, 141, 329, 987
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
496 : 1, 2, 4, 8, 16, 31, 62, 124, 248, 496
725 : 1, 5, 25, 29, 145, 725
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 392,987,980,496,725, is 1.
Now, the common factors can be found like this.
392:2x 2x 2x 7x 7
987:3x 7x 47
980:2x 2x 5x 7x 7
496:2x 2x 2x 2x 31
725:5x 5x 29
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 5x 7x 7x 7 = 54880
Therefore, the value for common factors is 54880.
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 = 136348064832000/(1x54880)
LCM = 136348064832000/54880
LCM = 2484476400
Thus, we can understand that the LCM of 392,987,980,496,725 is 2484476400.
