Given numbers are 392,994,722,360
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 392,994,722,360 is 452130840.
Find LCM of 392,994,722,360 with Prime Factorization
| 2 | 392, 994, 722, 360 |
| 2 | 196, 497, 361, 180 |
| 2 | 98, 497, 361, 90 |
| 7 | 49, 497, 361, 45 |
| 7, 71, 361, 45 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 7 x 71 x 361 x 45 = 452130840
Therefore, the lowest common multiple of 392,994,722,360 is 452130840.
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.
392 x 994 x 722 x 360 = 101277308160
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.
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
994 : 1, 2, 7, 14, 71, 142, 497, 994
722 : 1, 2, 19, 38, 361, 722
360 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 30, 36, 40, 45, 60, 72, 90, 120, 180, 360
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 392,994,722,360, is 2.
Now, the common factors can be found like this.
392:2x 2x 2x 7x 7
994:2x 7x 71
722:2x 19x 19
360:2x 2x 2x 3x 3x 5
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 2x 2x 7 = 112
Therefore, the value for common factors is 112.
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 = 101277308160/(2x112)
LCM = 101277308160/224
LCM = 452130840
Thus, we can understand that the LCM of 392,994,722,360 is 452130840.
