They are numbers that are NEAR PERFECT. a near perfect number is when its factors (exept the actual number) are added up and ALMOST equal the number ex. 16x1/2x8/4x4/ so its factors are 1,2,4,8 and 16 so add them ( exept the actual number) 1+2+4+8=15 so its NEAR PERFECT and a perfect number is a number that all its factors equal to its number ex. 6-1,2,3,6 are its factors all together-1+2+3=6 those are NEAR PERFECT and PERFECT numbers

Perfect number is a number whose factors other than itself add up to itself. For example 6 is perfect number because 1+2+3=6 where 1, 2 and 3 are its factors. But 8 is not perfect because 1+2+4 = 7. Other examples of perfect numbers are 28, 496 and 8128 etc.

Yes, 8 is a factor of 80 because if you times 8 with anither number, in this case, 10, you'd get 80, which is a perfect fit.

Perfect numbers are numbers where all the factors add to that number. For example 6's factors are 1,2, and 3 and 1+2+3=6. Therefore the next perfect number isn't until 28 which is 1,2, 4, 7, 14 where 1+2+4+7+14= 28 An almost perfect number is a number which, when adding all of its proper divisors (all divisors except himself), gives you one less, or one more then the number itlself. Up to now all known almost perfect numbers are 2^n. So to answer your question, the 2 almost perfect numbers between 5 and 20 are 8 and 16. Divisors of 8: 1,2,4 -----> 1+2+4=7 Divisors of 16: 1,2,4,8 -----> 1+2+4+8=15

64

No. The only known almost perfect numbers are the powers of 2, namely 1, 2, 4, 8, 16, 32, ...

If by 'perfect number' you mean 'perfect SQUARE', then yes. 49 is an odd number and a perfect square.

The sum of the 1st perfect number and 2nd perfect number is. . . 34!

64: 1, 2, 4, 8, 16, 32, 64Tip: To find the number, consider that if there are an odd number of factors, the number must be a perfect square, because a perfect square has one factor that is multiplied by itself. 64: 1, 2, 4, 8, 16, 32, 64Tip: To find the number, consider that if there are an odd number of factors, the number must be a perfect square, because a perfect square has one factor that is multiplied by itself.

496 is the third perfect number and 8128 is the fourth perfect number.

The square root of a perfect square is a whole number. Example sqrt(36) = 6 so 36 is a perfect square Example sqrt(25) = 5 so 25 is a perfect square Example sqrt(8)= 2.828 which is not whole so 8 is not a perfect square

No, at least, 70 isn't a perfect square. The nearest perfect squares are 8 squared = 64, and 9 squared = 81.

multiply the same number by itself, for example: 2*2=4, 4 is a perfect square. 8*8=64, 64 is a perfect square. the first few perfect squares are 1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144, 169, 196, 225,....

Yes, 64 is a perfect squarebecause 64 = 8*8
