Given numbers are 847,691,121,719
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 847,691,121,719 is 420814163.
Find LCM of 847,691,121,719 with Prime Factorization
| 11 | 847, 691, 121, 719 |
| 11 | 77, 691, 11, 719 |
| 7, 691, 1, 719 |
Multiply the prime numbers at the bottom and the left side.
11 x 11 x 7 x 691 x 1 x 719 = 420814163
Therefore, the lowest common multiple of 847,691,121,719 is 420814163.
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.
847 x 691 x 121 x 719 = 50918513723
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.
847 : 1, 7, 11, 77, 121, 847
691 : 1, 691
121 : 1, 11, 121
719 : 1, 719
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 847,691,121,719, is 1.
Now, the common factors can be found like this.
847:7x 11x 11
691:691
121:11x 11
719:719
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 11 = 121
Therefore, the value for common factors is 121.
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 = 50918513723/(1x121)
LCM = 50918513723/121
LCM = 420814163
Thus, we can understand that the LCM of 847,691,121,719 is 420814163.
