Two numbers have a sum of their LCM and HCF equal to 464, and their LCM is 28 times their HCF. One of the numbers is 64. Find the difference between the...
Let N be the greatest number that will divide 86, 120, 154 leaving the same remainder in each case. Then sum of the digits in N is:
The least number which when divided by 6, 8, 9 and 12 leave zero remainder in each case and when divided by 13 leaves a remainder of 7 is:
The H.C.F. of two numbers is 16 and the other two factors of their L.C.M. are 4 and 13. The larger of the two numbers is:
The LCM of two numbers is 4 times of their HCF. The sum of LCM and HCF is 280. If one of the number is 224, then the other number is:
