Quantitative Apitude-H.C.F & L.C.M. of Numbers
11. The sum of two numbers is 528 and their H.C.F. is 33.The number of pairs of such numbers satisfying the above condition is :
- 6
- 12
- 8
- 4
12. The product of two 2-digit number is 2028 and their G.C.M. IS 13. The number are:
- 26, 78
- 39, 52
- 13, 156
- 36, 68
13. The H.C.F. of two numbers is 12 and their difference is 12. The numbers are :
- 66, 78
- 70, 82
- 94, 106
- 84, 96
14. The H.C.F. of two numbers is 11 and their L.C.M. is 7700. If one these numbers is 275, then the other one is :
- 279
- 283
- 308
- 318
15. The L.C.M. of two number is 45 times their H.F.C. If one of the numbers is 125 and the sum of H.C.F. and L.C.M. is 1150, the other number is :
- 215
- 220
- 225
- 235
16. About the number of pairs which have 16 as their H.C.F. and 136 their L.C.M. we can definitely say that :
- Only oe such par exists
- Only two such pairs exist
- Many such pairs exist
- No such pair exists
17. The L.C.M. and L.C.M. of two numbers are 50 and 250 respectively If the first number is divided by 2, the quotient is 50. the secnd number is :
- 50
- 100
- 125
- 250
18. The product of two numbers is 1320 and their H.C.F. is 6. The L.C.M of the numbers is:
- 7920
- 220
- 1314
- 1326
20. The largest number which divides 25, 73 and 97 to leave the same remainder in each case is :
- 24
- 23
- 21
- 6
