Required product = 7 x 4 = 28.
The least number which when divided by 5, 15 and 25 leave a same remainder 2 in each case?
If the sum of 2 numbers is 185, their LCM is 1700 and HCF is 5. Then the difference between 2 numbers is:
Let N be the greatest number that will divide 78, 109, 140 leaving the same remainder in each case. Then sum of the digits in N is:
The sum of two numbers is 126 and their HCF is 14. Total number of such pairs of numbers is?
The HCF of any set of 10 co-prime numbers is always:
