Given numbers are 719,644,791,906,145
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 719,644,791,906,145 is 3436840721580.
Find LCM of 719,644,791,906,145 with Prime Factorization
| 2 | 719, 644, 791, 906, 145 |
| 7 | 719, 322, 791, 453, 145 |
| 719, 46, 113, 453, 145 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 719 x 46 x 113 x 453 x 145 = 3436840721580
Therefore, the lowest common multiple of 719,644,791,906,145 is 3436840721580.
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.
719 x 644 x 791 x 906 x 145 = 48115770102120
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.
719 : 1, 719
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
791 : 1, 7, 113, 791
906 : 1, 2, 3, 6, 151, 302, 453, 906
145 : 1, 5, 29, 145
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 719,644,791,906,145, is 1.
Now, the common factors can be found like this.
719:719
644:2x 2x 7x 23
791:7x 113
906:2x 3x 151
145:5x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7 = 14
Therefore, the value for common factors is 14.
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 = 48115770102120/(1x14)
LCM = 48115770102120/14
LCM = 3436840721580
Thus, we can understand that the LCM of 719,644,791,906,145 is 3436840721580.
