5x2=10 10-3=7 7x4=28
5 x 3! - (4 - 2) = 30 - 2 = 28 5 x 3! - (4 ÷ 2) = 30 - 2 = 28 (2 x 3 x 5) - √4 = 30 - 2 = 28

This sort of number is a factor, which means 28 can be divided by the number and the quotient will have no remainder. Factors of 28 are 28, 14, 7, 4, 2, and 1.
2^3+(4*5)=8+20=28
Well, let's paint a happy little picture with prime numbers! To find the Least Common Multiple (LCM) of 12, 28, and 40, we first break down each number into its prime factors: 12 = 2^2 * 3, 28 = 2^2 * 7, and 40 = 2^3 * 5. Then, we take the highest power of each prime factor that appears in any of the numbers, which gives us 2^3 * 3 * 5 * 7 = 840. So, the LCM of 12, 28, and 40 using prime numbers is 840.
They are: 2+3+5+7+11 = 28
31-3+2=30 31-3=28 28+2=30 17 + 11 + 2
5x2=10 10-3=7 7x4=28
By using: (3*6)+(3*2) = 24
5 x 3! - (4 - 2) = 30 - 2 = 28 5 x 3! - (4 ÷ 2) = 30 - 2 = 28 (2 x 3 x 5) - √4 = 30 - 2 = 28

average of first five prime numbers = 5.6 first five prime numbers = 2, 3, 5, 7, 11average = sum of first prime numbers/5= (2 + 3 + 5 + 7 + 11)/5= 28/5= 5.6
28 = 22 × 7 42 = 2 × 3 × 7
Oh, what a happy little math problem we have here! To get to 28 using the numbers 3, 2, 6, and 8, we can simply multiply 3 by 2 to get 6, then add 6 and 8 to get 14, and finally multiply 14 by 2 to reach 28. Just like painting, sometimes all it takes is a few simple steps to create something wonderful!
21+3 or using all the numbers: 21 + (3*(2-1))
