Solution:
The given series is -- 117, 92, 67, X , 17, -8
Consequtive numbers decreases by 25
Following this pattern, the Missing Number X should decrease by 25 from the previous number.
When we subract 25 to the number before X (i.e 67) we get 67--25=42

View Answer
Solution:
The Least Common Multiple (L.C.M) of 3 and 41 can be computed by using the greatest common factor ie., GCF of 3 and 41. This is the easiest approach:
L.C.M(3,41) = (3 X 41) / GCF (3,41)
= 123 / 1
= 123

View Answer
Solution:
Factors of 36 = 1, 2, 3, 4, 6, 9.
Factors of 14 = 1, 2, and 7.
Therefore, common factor of 36 and 14 = 1 and 2
Highest common factor (H.C.F) of 36 and 14 = 2.
Therefore, 2 is H.C.F. or G.C.D. greatest common divisor of 36 and 14.
H.C.F. or G.C.D. of given numbers is the greatest number which divides all the numbers without leaving a remainder.
