No, because 4 is not a factor of 14, for example.The rule for finding if a number is a multiple of 4 is: If the last 2 digits of the number are a multiple of 4, then the number is a multiple of 4.Example: here are some multiples of 4: 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48, 52, 56, 60, 64, 68, 72, 76, 80, 84, 88, 92, 96, 100so if the last 2 digits of the number are 04, 08, 16, ...., 96, or 00, then the number is a multiple of 4 (or you can say that 4 is a factor)234535721117575672 has 4 as a factor, because 72 are the last 2 digits.Rather than memorize all multiples of 4 to 100, just remember this:if the 'ones' digit is a 0, 4, or 8, then the 'tens' digit must be even (zero being even): example, 20, 48, 64if the 'ones' digit is a 2 or 6, then the 'tens' digit must be odd.example 16, 52, 36No. 4 and 24 have a factor of 4, but 14 and 34 do not.
The least common multiple of 4, 5, and 8 is 40.

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
When the tens digit is even and the units digit is 0, 4 or 8 or the tens digit is odd and the units digit is 2 or 6.

8 x 12 which equals 96
The largest 8-digit number is 9,999,999.
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.
