Given numbers are 715,703,869,343
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 715,703,869,343 is 13620171565.
Find LCM of 715,703,869,343 with Prime Factorization
11 | 715, 703, 869, 343 |
65, 703, 79, 343 |
Multiply the prime numbers at the bottom and the left side.
11 x 65 x 703 x 79 x 343 = 13620171565
Therefore, the lowest common multiple of 715,703,869,343 is 13620171565.
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.
715 x 703 x 869 x 343 = 149821887215
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.
715 : 1, 5, 11, 13, 55, 65, 143, 715
703 : 1, 19, 37, 703
869 : 1, 11, 79, 869
343 : 1, 7, 49, 343
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 715,703,869,343, is 1.
Now, the common factors can be found like this.
715:5x 11x 13
703:19x 37
869:11x 79
343:7x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11 = 11
Therefore, the value for common factors is 11.
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 = 149821887215/(1x11)
LCM = 149821887215/11
LCM = 13620171565
Thus, we can understand that the LCM of 715,703,869,343 is 13620171565.
