two numbers are co-prime if their hcf is 1.
let us find the hcf of 231 and 396.
applying the Euclid’s division lemma:
the HCF of 231 and 396 is 33.
thus the numbers 231 and 396 are not co-primes.
answer:
(1,2,3,4,5,6,7,8,9,10)
2=2
3=3
4=2*2
5=5
6=2*3
7=7
8=2*2*2
9=3*3
10=2*5
Look for the max. # of times each prime is used.
N=(2*2*2)*(3*3)*5*7=2520
