If the 2 digit number is a multiple of both 5 and 7 then it is a multiple of (5 x 7) which equals 35. The only even 2 digit number which is a multiple of 35 is, 2 x 35 = 70
# The prime factors of 24 are 2, 2, 2, and 3. # The prime factors of 50 are 2, 5 and 5. # Therefore the Lowest Common Multiple of 24 and 50 is made up of 2, 2, 2, 3, 5 and 5. # 2 x 2 x 2 x 3 x 5 x 5 = 600 As 99,999 is the largest 5-digit number we need to divide 99,999 by 600 and then use the integer part of the result as follows. 99,999 ÷ 600 = 166.665 If we ignore the decimal portion of the number and multiply the 166 by 600 we get the largest multiple of 600 which is still a 5-digit number. 166 x 600 = 99,600

To find the largest 2-digit number that is a factor of 3375, we need to factorize 3375 into its prime factors. 3375 can be expressed as 3^3 * 5^3. To find the largest 2-digit number that is a factor, we need to consider the factors that are multiples of both 3 and 5. The largest 2-digit number that fits this criteria is 75, which is 3 * 5^2.
