The largest 4 digit number in base 8 is 77778 (= 409510).
A number is a multiple of 4 if the last 2 digits are a multiple of 4 The 10s digit is even and the last digit is 0, 4 or 8 The 10s digit is odd and the last digit is 2 or 6 A number is a multiple of 8 if the last 3 digits are a multiple of 8 The 100s digit is even and the last 2 digits are a multiple of 8 The 100s digit is odd and the last 2 digits are 4 times an odd number
8*number = 3-digit number start by knowing basic times tables 1 through 9 8, 16, 24, 32, 40, 48, 56, 64, 72 8*100 = 800 8*30 = 240 8*130 = 1040 8*20 = 160 8*120 = 960 8*4 = 32 8*124 = 992 the largest 3-digit number that is a multiple of 8 is 992

To find a 4-digit number that is divisible by both 8 and 9, we need to find a number that is a multiple of the least common multiple of 8 and 9, which is 72. Starting from the smallest 4-digit multiple of 72, which is 1008, we can find the next number by adding 72 until we reach a 4-digit number. Therefore, the smallest 4-digit number that is divisible by both 8 and 9 is 1008.
8 x 12 which equals 96
All multiples of their LCM is divisible by them. lcm(8, 7, 6, 5, 4, 3, 2, 1) = 840 therefore need the largest multiple of 840 which is a 3-digit number = 840 x 1 = 840.
The largest 8-digit number is 9,999,999.
