Given numbers are 722,361,403,775
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 722,361,403,775 is 7274150.
Find LCM of 722,361,403,775 with Prime Factorization
| 19 | 722, 361, 403, 775 |
| 19 | 38, 19, 403, 775 |
| 31 | 2, 1, 403, 775 |
| 2, 1, 13, 25 |
Multiply the prime numbers at the bottom and the left side.
19 x 19 x 31 x 2 x 1 x 13 x 25 = 7274150
Therefore, the lowest common multiple of 722,361,403,775 is 7274150.
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 361 x 403 x 775 = 81405012650
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
361 : 1, 19, 361
403 : 1, 13, 31, 403
775 : 1, 5, 25, 31, 155, 775
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 722,361,403,775, is 1.
Now, the common factors can be found like this.
722:2x 19x 19
361:19x 19
403:13x 31
775:5x 5x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
19x 19x 31 = 11191
Therefore, the value for common factors is 11191.
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 = 81405012650/(1x11191)
LCM = 81405012650/11191
LCM = 7274150
Thus, we can understand that the LCM of 722,361,403,775 is 7274150.
