Find LCM of 974,387,990,335,393 with Prime Factorization
| 2 | 974, 387, 990, 335, 393 |
| 3 | 487, 387, 495, 335, 393 |
| 3 | 487, 129, 165, 335, 131 |
| 5 | 487, 43, 55, 335, 131 |
| 487, 43, 11, 67, 131 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 487 x 43 x 11 x 67 x 131 = 181961165430
Therefore, the lowest common multiple of 974,387,990,335,393 is 181961165430.
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.
974 x 387 x 990 x 335 x 393 = 49129514666100
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.
974 : 1, 2, 487, 974
387 : 1, 3, 9, 43, 129, 387
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
335 : 1, 5, 67, 335
393 : 1, 3, 131, 393
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 974,387,990,335,393, is 1.
Now, the common factors can be found like this.
974:2x 487
387:3x 3x 43
990:2x 3x 3x 5x 11
335:5x 67
393:3x 131
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 5 = 270
Therefore, the value for common factors is 270.
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 = 49129514666100/(1x270)
LCM = 49129514666100/270
LCM = 181961165430
Thus, we can understand that the LCM of 974,387,990,335,393 is 181961165430.
