From 100 to 200, how many numbers are divided by 5 but not by 5 and 7? May 6 | Mahamud from Schenectady, NY | 1 Answer | 0 Votes Mark favorite Subscribe Comment
18. Between 100 and 200, only 105, 140, and 175 are divisible by 5 and 7. May 6 | Ashley H. Comment Comments Any formula for these types of maths????? May 6 | Mahamud from Schenectady, NY Basically this boils down to the first common multiple of 5 and 7 being 35, so we're eliminating multiples of 35 from between 100 and 200. Every other multiple of 5 passes the test. Hope that helps, Will May 6 | William M. Very well said. :-) May 6 | Ashley H. Comment
