Given numbers are 740,390,991,344,401
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 740,390,991,344,401 is 986308566360.
Find LCM of 740,390,991,344,401 with Prime Factorization
| 2 | 740, 390, 991, 344, 401 |
| 2 | 370, 195, 991, 172, 401 |
| 5 | 185, 195, 991, 86, 401 |
| 37, 39, 991, 86, 401 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 37 x 39 x 991 x 86 x 401 = 986308566360
Therefore, the lowest common multiple of 740,390,991,344,401 is 986308566360.
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.
740 x 390 x 991 x 344 x 401 = 39452342654400
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.
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
991 : 1, 991
344 : 1, 2, 4, 8, 43, 86, 172, 344
401 : 1, 401
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 740,390,991,344,401, is 1.
Now, the common factors can be found like this.
740:2x 2x 5x 37
390:2x 3x 5x 13
991:991
344:2x 2x 2x 43
401:401
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 2x 5 = 40
Therefore, the value for common factors is 40.
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 = 39452342654400/(1x40)
LCM = 39452342654400/40
LCM = 986308566360
Thus, we can understand that the LCM of 740,390,991,344,401 is 986308566360.
