Given numbers are 790,604,711,904
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 790,604,711,904 is 485271720.
Find LCM of 790,604,711,904 with Prime Factorization
| 2 | 790, 604, 711, 904 |
| 2 | 395, 302, 711, 452 |
| 79 | 395, 151, 711, 226 |
| 5, 151, 9, 226 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 79 x 5 x 151 x 9 x 226 = 485271720
Therefore, the lowest common multiple of 790,604,711,904 is 485271720.
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.
790 x 604 x 711 x 904 = 306691727040
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.
790 : 1, 2, 5, 10, 79, 158, 395, 790
604 : 1, 2, 4, 151, 302, 604
711 : 1, 3, 9, 79, 237, 711
904 : 1, 2, 4, 8, 113, 226, 452, 904
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 790,604,711,904, is 1.
Now, the common factors can be found like this.
790:2x 5x 79
604:2x 2x 151
711:3x 3x 79
904:2x 2x 2x 113
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 79 = 632
Therefore, the value for common factors is 632.
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 = 306691727040/(1x632)
LCM = 306691727040/632
LCM = 485271720
Thus, we can understand that the LCM of 790,604,711,904 is 485271720.
