Given numbers are 722,738,129,923,492
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 722,738,129,923,492 is 21147728004.
Find LCM of 722,738,129,923,492 with Prime Factorization
| 2 | 722, 738, 129, 923, 492 |
| 3 | 361, 369, 129, 923, 246 |
| 41 | 361, 123, 43, 923, 82 |
| 361, 3, 43, 923, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 41 x 361 x 3 x 43 x 923 x 2 = 21147728004
Therefore, the lowest common multiple of 722,738,129,923,492 is 21147728004.
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.
722 x 738 x 129 x 923 x 492 = 31214046533904
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.
722 : 1, 2, 19, 38, 361, 722
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
129 : 1, 3, 43, 129
923 : 1, 13, 71, 923
492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 722,738,129,923,492, is 1.
Now, the common factors can be found like this.
722:2x 19x 19
738:2x 3x 3x 41
129:3x 43
923:13x 71
492:2x 2x 3x 41
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 3x 3x 41 = 1476
Therefore, the value for common factors is 1476.
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 = 31214046533904/(1x1476)
LCM = 31214046533904/1476
LCM = 21147728004
Thus, we can understand that the LCM of 722,738,129,923,492 is 21147728004.
