my number is less than 100 one more than a multiple of 3 one of its digits is prime if you reverse its digits you get a prime it has exactly four factors the sum of digits is prime if you miltiply it by 5 it is greater than 100
ON THE NUMERS 10 AND 100, HOW MANY OF THEM ARE PALINDROMES? PLEASE LIST THEM FIND PALINDROMES THAT ARE: A MULTIPLE OF 3 A MULTIPLE OF 4 A MULTIPLE OF 9 A MULTIPLE OF 12 A SQUARE NUMBER A TRIANGULAR NUMBER I will do one or two. 33
how would i find least common multiple of 20, 50 and 3 ? okay well you take the 50 and times it by ever number 50--> is it divisbile by 3 NO so not the least common multiple 50x2=100 --> is it divisible by 3 NO, so not the least

I am a positive integer less than 100. two more than my value is a multiple of 6. the sum of my digits is a multiple of 7. I must show all my work This kind of problem can't be solved by writing and solving one or two equations.
What is my number? clue 1. my number is a multiple of 2 and 7 clue 2. My number is less than 100 but larger than 50. clue 3. My number is the product of three primes, which are all different. Can some one tell me how to work this
Since when is 5^7 =8125? if a number is a multple of ten, that means the last digit is zero. The leading digit cannot be zero. 9*10^5*1 on c, again, the leading digit cannot be zero. d is right e. no leading zero is allowed.
