700 and 1400 have an LCM of 700.
To find the least common multiple (LCM) of two consecutive numbers that is greater than 200 and is a multiple of 7, we need to consider the properties of consecutive numbers and multiples of 7. Since the LCM must be greater than 200 and a multiple of 7, the two consecutive numbers must be 28 and 29. The LCM of 28 and 29 is 812, which is greater than 200 and a multiple of 7.
Find either the least common multiple, or any common multiple, of those three numbers. One way to get a common multiple is to simply multiply the numbers together. Then try multiplying that multiple by different integers, until you find one that is greater than 200.
14 and 15
Consecutive numbers can't both be multiples of 7. The LCM of consecutive numbers is their product. 14 and 15 are consecutive numbers whose LCM is a multiple of 7 that is greater than 200.
It is: 67*3 = 201
First odd number greater than 20 is 21 Last odd number less than 200 is 199 → number of odd numbers between 20 and 200 is (199 - 21) ÷ 2 + 1 = 90
Prime numbers are 151, 157, 163, 167, 173, 179,181,191,193,197,199,
15
Any even number greater than 2.
35 and 119.
The smallest multiple of 7 that's larger than 1 is the first multiple . . . 7.The largest multiple of 7 that's smaller than 200 is the 28th multiple . . . 196 .So there are 28 of them in that range.
