Given numbers are 904,965,965,690
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 904,965,965,690 is 60192840.
Find LCM of 904,965,965,690 with Prime Factorization
| 2 | 904, 965, 965, 690 |
| 5 | 452, 965, 965, 345 |
| 193 | 452, 193, 193, 69 |
| 452, 1, 1, 69 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 193 x 452 x 1 x 1 x 69 = 60192840
Therefore, the lowest common multiple of 904,965,965,690 is 60192840.
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.
904 x 965 x 965 x 690 = 580860906000
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.
904 : 1, 2, 4, 8, 113, 226, 452, 904
965 : 1, 5, 193, 965
965 : 1, 5, 193, 965
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 904,965,965,690, is 1.
Now, the common factors can be found like this.
904:2x 2x 2x 113
965:5x 193
965:5x 193
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 5x 5x 193 = 9650
Therefore, the value for common factors is 9650.
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 = 580860906000/(1x9650)
LCM = 580860906000/9650
LCM = 60192840
Thus, we can understand that the LCM of 904,965,965,690 is 60192840.
