Given numbers are 392,779,323,457
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 392,779,323,457 is 2372403992.
Find LCM of 392,779,323,457 with Prime Factorization
19 | 392, 779, 323, 457 |
392, 41, 17, 457 |
Multiply the prime numbers at the bottom and the left side.
19 x 392 x 41 x 17 x 457 = 2372403992
Therefore, the lowest common multiple of 392,779,323,457 is 2372403992.
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 779 x 323 x 457 = 45075675848
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
779 : 1, 19, 41, 779
323 : 1, 17, 19, 323
457 : 1, 457
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 392,779,323,457, is 1.
Now, the common factors can be found like this.
392:2x 2x 2x 7x 7
779:19x 41
323:17x 19
457:457
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
19 = 19
Therefore, the value for common factors is 19.
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 = 45075675848/(1x19)
LCM = 45075675848/19
LCM = 2372403992
Thus, we can understand that the LCM of 392,779,323,457 is 2372403992.
