When testing for numbers that 'go into' Test wi the Prime Numbers:- #1; Is it an even number . In thisd case No. so discoiunt '2' #2; Does it end in '5' or '10' . In this case NO so discount '5' #3 ; Do the digits add to '9' . In this case YES 2+6+1 = 9 , so it will divide by '9'. #4 ; '3' & '7' are the only other two possibilites, however, they will be manually tested. Hence 261/9 = 29 261/ 3 = 87 261/7 = 37. remainder '2' So '7' DOESN'T Go Hence '3' & '9' will go into 261. The other unique number is '11' . e.g. 132 . To test if the middle number add to the sum of the outside numbers , in this 1 + 2 = 3 the it will divide by '11' Try 143 , or 275

571 + 261 = 832
the two numbers that go into 96 are i dont know lol
1 and 343 are two numbers that do.
The only common factor is one.
For any two natural numbers a and b, if adivides b then a is the factor of b.Here 3 divides 261 that's why 3 is a factor of 261.

The following numbers (factors) divide evenly into 261: 1, 3, 9, 29, 87, 261.
261,000,000
87 does... 3 times
Called 'factors', the positive whole numbers that go into 522 evenly are: 1, 2, 3, 6, 9, 18, 29, 58, 87, 174, 261, 522.
571 + 261 = 832
the two numbers that go into 96 are i dont know lol
The mean of these numbers is 100 + 150 + 252 + 261 + 270 = 1033/5 = 206.6
