The researchers at IIT Guwahati have created a fermentation process that uses ultrasound to safely generate Xylitol from sugarcane bagasse, the byproduct of crushing sugar cane.
Find the HCF of 932 and 748.
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:
The least number which when divided by 3, 6, 9 and 12 leave zero remainder in each case and when divided by 16 leaves a remainder of 3 is:
The HCF and LCM of two numbers, A and B, are 9 and 162, respectively. The difference between these two numbers is 27. Find their sum.
Let N be the greatest number that will divide 72, 105, 138 leaving the same remainder in each case. Then sum of the digits in N is:
The HCF and LCM of two natural numbers are 16 and 44, respectively. What is the difference between the two numbers, if one of the numbers is 22?
A number is three times another number and their HCF is 8. What is the sum of the squares of the numbers?
