There cannot be common factors of just one number. To be common there need to be at least two numbers.
Since 38 x 25 = 950, 38 and 25 are factors of 950 (38,25) is a factor pair of 950. 38 x 25 is a factor string of 950.
The oldest and most common jewelry alloy for platinum is 90% platinum, 10% iridium. You'll see various stamps, the most common maybe is 10% Ir Plat or something like that. Occasionally it's all spelled out, too. A newer alloy is 950 platinum, where the other 50 is usually cobalt. Usually that is stamped 950 Plat. or 950 Platinum. Those are the two most common, anyway.
They can be many prices but the most common prices are: $650 $950 $550
The positive integer factors of 950 are:1, 2, 5, 10, 19, 25, 38, 50, 95, 190, 475, 950There are infinitely many sets.One such is {1, 1, 1, 1, ... , 1, 950}
The factor pairs of 950 are: 950,1 / 475,2 / 190,5 / 95,10 / 50,19 / 38,25
The common factors are: 1, 2.
950 / 380 = 2 r 190 380 / 190 = 2 r 0 gcf of 380 and 950 is 190.
