Given numbers are 719,721,144,987,122
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 719,721,144,987,122 is 214019990352.
Find LCM of 719,721,144,987,122 with Prime Factorization
| 2 | 719, 721, 144, 987, 122 |
| 3 | 719, 721, 72, 987, 61 |
| 7 | 719, 721, 24, 329, 61 |
| 719, 103, 24, 47, 61 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 719 x 103 x 24 x 47 x 61 = 214019990352
Therefore, the lowest common multiple of 719,721,144,987,122 is 214019990352.
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 721 x 144 x 987 x 122 = 8988839594784
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
721 : 1, 7, 103, 721
144 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144
987 : 1, 3, 7, 21, 47, 141, 329, 987
122 : 1, 2, 61, 122
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 719,721,144,987,122, is 1.
Now, the common factors can be found like this.
719:719
721:7x 103
144:2x 2x 2x 2x 3x 3
987:3x 7x 47
122:2x 61
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 7 = 42
Therefore, the value for common factors is 42.
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 = 8988839594784/(1x42)
LCM = 8988839594784/42
LCM = 214019990352
Thus, we can understand that the LCM of 719,721,144,987,122 is 214019990352.
