find the LCM of 58 and 32
32=2x2x2x2x2
58=2x29
LCM=2x2x2x2x2x29=928
add 44 to 928 so that when 928 is divided by 58 there will be a remainder of 44
928+44=972
when you divide the number you want by 32 and get a remainder of 30 the remainder will be 30/32=0.9375 as a decimal
972/32=30.375, wrong answer
subtract 58 from 972 to get 914
914/32=28.5625, wrong answer
note: every time you subtract 58, you get a number that, when divided by 58, leaves a remainder of 44
914-58=856 and 856/32=26.75, wrong answer
856-58=798
798 when divided by 58 leaves 44 (798/58=13 R44)
798/32=24.9375 which is what you want
798/32=24 R30
the number you are looking for is 798
note: there are others also
use the same reasoning
3*the LCM is 2784 is where to start...
doing the work...
2654 is another
2*the LCM=1856
doing the work...
1726 is another
