Question

LCM of tow number x and y is 1296 and their HCF is 36 how many order pair of x,y can be formed​

Answer 1

Answer:

36 . 1296

144 , 324

Step-by-step explanation:

LCM of tow number x and y is 1296 and their HCF is 36 how many order pair of x,y can be formed​

LCM - 1296

HCF = 36

xy = 1296 * 36

As 36 is HCF so 36 should be a factor in x & y both

1296  = 36 * 36

one 36 is for HCF

and another 36 should have co - prime factors as HCF is 36 only

36 = 1 * 36

36 = 4 * 9

36 =  2 * 18 , 3 * 12  & 6 *6 ( these are neglected as these have common Factors so HCF will increase)

one Pairs  =  36 *1   & 36 * 36   =  36 & 1296

Another Pair = 36*4  & 36 * 9  = 144  &  324
