Given numbers are 760,703,715,649
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 760,703,715,649 is 237248440.
Find LCM of 760,703,715,649 with Prime Factorization
| 5 | 760, 703, 715, 649 |
| 11 | 152, 703, 143, 649 |
| 19 | 152, 703, 13, 59 |
| 8, 37, 13, 59 |
Multiply the prime numbers at the bottom and the left side.
5 x 11 x 19 x 8 x 37 x 13 x 59 = 237248440
Therefore, the lowest common multiple of 760,703,715,649 is 237248440.
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.
760 x 703 x 715 x 649 = 247924619800
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.
760 : 1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760
703 : 1, 19, 37, 703
715 : 1, 5, 11, 13, 55, 65, 143, 715
649 : 1, 11, 59, 649
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 760,703,715,649, is 1.
Now, the common factors can be found like this.
760:2x 2x 2x 5x 19
703:19x 37
715:5x 11x 13
649:11x 59
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 11x 19 = 1045
Therefore, the value for common factors is 1045.
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 = 247924619800/(1x1045)
LCM = 247924619800/1045
LCM = 237248440
Thus, we can understand that the LCM of 760,703,715,649 is 237248440.
