Given numbers are 942,392,922,721,916
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 942,392,922,721,916 is 2007615807624.
Find LCM of 942,392,922,721,916 with Prime Factorization
| 2 | 942, 392, 922, 721, 916 |
| 2 | 471, 196, 461, 721, 458 |
| 7 | 471, 98, 461, 721, 229 |
| 471, 14, 461, 103, 229 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 471 x 14 x 461 x 103 x 229 = 2007615807624
Therefore, the lowest common multiple of 942,392,922,721,916 is 2007615807624.
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.
942 x 392 x 922 x 721 x 916 = 224852970453888
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.
942 : 1, 2, 3, 6, 157, 314, 471, 942
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
922 : 1, 2, 461, 922
721 : 1, 7, 103, 721
916 : 1, 2, 4, 229, 458, 916
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 942,392,922,721,916, is 1.
Now, the common factors can be found like this.
942:2x 3x 157
392:2x 2x 2x 7x 7
922:2x 461
721:7x 103
916:2x 2x 229
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 = 224852970453888/(1x112)
LCM = 224852970453888/112
LCM = 2007615807624
Thus, we can understand that the LCM of 942,392,922,721,916 is 2007615807624.
