Read Solution (Total 3)
-
- lcm of (1,2,...86) and lcm of (1,2,... 83) is same bcz..
lcm is the highest common prime factors so
lcm of 1st 96 no= 2^6 * 3^4 * 5^2 * 7^2 * 11 *13 *17 *19 *23 *29 *31 *37 *41 *43 *47 *53 *59 *61 *67 *71 *73 *79 *83)
lcm of 83 no are also same bcz they have same prime factors..
so (L.C.M OF 86)/(LCM OF 83) =1
i.e.,quotient=1 - 11 years agoHelpfull: Yes(18) No(0)
- quotient is 1..coz both the lcm will b same
