245 is not prime. Composite: (5 x 49 or 5 x 7 x 7) Also you can automatically determine a number as composite if: it ends with 2, 4, 6, 8, and 0: multiples of 2; or it ends with 5: multiples of 5.
The composite factors of 735 are 15, 21, 35, 49, 105, 147, 245, 735

245 + 245 + 245 = 735

20 percent off of 245 dollars = 19620% off of $245= 20% discount applied to $245= $245 - (20% * $245)= $245 - (0.20 * $245)= $245 - 49= 196
LCM of a prime number and a composite number is equal to their product if the latter is not divisible by the former. 5 is a prime number and 49 is a composite number. 49 is not divisible by 5. So, LCM(5,49) = 5 x 49 = 245. Actually the reason behind this is that both(5 and 49) do not share any common factors except 1, so the LCM is equal to the product.
