Factors of 20 are 1, 2, 4, 5, 10 and 20. And their sum is 1 + 2 + 4 + 5 + 10 + 20 = 32.
(1,20),2,10,4,5
The last digit in the product of the first 20 odd natural numbers can be determined by looking at the pattern of the units digit in the multiplication of consecutive odd numbers. The units digit of the product of consecutive odd numbers alternates between 1 and 5. Since there are 10 odd numbers between 1 and 19, and 20 is also an odd number, the last digit in the product of the first 20 odd natural numbers is 5.
There is no such combination to form an even no. 20 by combing 5 odd nos. as odd+odd=even even +even=evenodd+even=odd even+odd=odd adding 5 odd like
because you have a number times itself 6x6.
NO because 5 is a factor of 20 and its odd
The factors of 20 are 1,2,4,5,10 and 20. Two are odd, four are even.
Yes, the factors of all odd numbers are odd numbers.
Because 55 is an odd number. All the factors of odd numbers are odd.
48 has both even and odd factors.
All odd numbers have odd factors.
All nonzero numbers have factors. Some factors are even numbers, some factors are odd numbers.
Any odd number.
3,7,11,13
All of the odd numbers in that range can be factors.
All nonzero numbers have factors. Some factors are odd numbers. 3 is an odd factor of 12.
The odd factors of 70 are: 1, 5, 7, and 35. The sum of these factors is 48.
