Given numbers are 754,835,904,690
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 754,835,904,690 is 19635652920.
Find LCM of 754,835,904,690 with Prime Factorization
| 2 | 754, 835, 904, 690 |
| 5 | 377, 835, 452, 345 |
| 377, 167, 452, 69 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 377 x 167 x 452 x 69 = 19635652920
Therefore, the lowest common multiple of 754,835,904,690 is 19635652920.
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.
754 x 835 x 904 x 690 = 392713058400
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.
754 : 1, 2, 13, 26, 29, 58, 377, 754
835 : 1, 5, 167, 835
904 : 1, 2, 4, 8, 113, 226, 452, 904
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 754,835,904,690, is 1.
Now, the common factors can be found like this.
754:2x 13x 29
835:5x 167
904:2x 2x 2x 113
690:2x 3x 5x 23
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 5 = 20
Therefore, the value for common factors is 20.
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 = 392713058400/(1x20)
LCM = 392713058400/20
LCM = 19635652920
Thus, we can understand that the LCM of 754,835,904,690 is 19635652920.
