Question

If LCM of 9, 12 and n is 252. Of n is a odd , find all the possible values of n.

Answer 1

Answer:

we have LCM of 9 ,12 and n as 252

first, make factors of 252

252=2×2×3×3×7

we also know ,n is odd

so n can't be 2

thus n can be 7 ,or 21

as both no 9 and 12 does not have 7

so n must be odd multiple of 7

Answer 2

Answer:

here,

9 = 3×3

12= 2×2×3

n=252

=2×2×3×3×7

=3×3×3×3×3×7

the possible value of n are 2^2×3^5×7
