Given numbers are 781,654,904,174,703
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 781,654,904,174,703 is 4706743591176.
Find LCM of 781,654,904,174,703 with Prime Factorization
| 2 | 781, 654, 904, 174, 703 |
| 3 | 781, 327, 452, 87, 703 |
| 781, 109, 452, 29, 703 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 781 x 109 x 452 x 29 x 703 = 4706743591176
Therefore, the lowest common multiple of 781,654,904,174,703 is 4706743591176.
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.
781 x 654 x 904 x 174 x 703 = 56480923094112
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.
781 : 1, 11, 71, 781
654 : 1, 2, 3, 6, 109, 218, 327, 654
904 : 1, 2, 4, 8, 113, 226, 452, 904
174 : 1, 2, 3, 6, 29, 58, 87, 174
703 : 1, 19, 37, 703
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,654,904,174,703, is 1.
Now, the common factors can be found like this.
781:11x 71
654:2x 3x 109
904:2x 2x 2x 113
174:2x 3x 29
703:19x 37
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 3 = 12
Therefore, the value for common factors is 12.
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 = 56480923094112/(1x12)
LCM = 56480923094112/12
LCM = 4706743591176
Thus, we can understand that the LCM of 781,654,904,174,703 is 4706743591176.
