Given numbers are 722,262,551,406
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 722,262,551,406 is 19200146.
Find LCM of 722,262,551,406 with Prime Factorization
| 2 | 722, 262, 551, 406 |
| 19 | 361, 131, 551, 203 |
| 29 | 19, 131, 29, 203 |
| 19, 131, 1, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 19 x 29 x 19 x 131 x 1 x 7 = 19200146
Therefore, the lowest common multiple of 722,262,551,406 is 19200146.
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 262 x 551 x 406 = 42317121784
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
262 : 1, 2, 131, 262
551 : 1, 19, 29, 551
406 : 1, 2, 7, 14, 29, 58, 203, 406
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 722,262,551,406, is 1.
Now, the common factors can be found like this.
722:2x 19x 19
262:2x 131
551:19x 29
406:2x 7x 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 2x 19x 29 = 2204
Therefore, the value for common factors is 2204.
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 = 42317121784/(1x2204)
LCM = 42317121784/2204
LCM = 19200146
Thus, we can understand that the LCM of 722,262,551,406 is 19200146.
