What is the multiplies of 50 and 25?

Answer 1

Are you talking about multiples or factors? Multiples of 25 would be 25, 50, 75, 100, 125, and so on. Multiples of 50 would be 50, 100, 150, and so on. I've never heard ot that being asked.

prime facotrs of 25 would be 5,5. prime factors of 50 would be 2,5,5.

Answer 2

Average of (25*1, 25*2, ... , 25*50)

= 25 * Average of (1, 2, ... , 50)

= 25 * Sum of (1, 2, ... , 50)/50

= 0.5 * Sum of (1, 2, ... , 50)

= 0.5*50*51/2

= 25*51/2

= 637.5
