The HCF of two numbers is 18 and their LCM is 540. If one of the numbers is 90, find the other number.
The LCM of two natural numbers is 10 times their HCF. If the product of given two numbers is 1000, then find the LCM of the numbers.Â
The ratio of three numbers is 7:3:2. If their HCF is 4, find the LCM of the numbers.
The LCM and the HCF of the numbers 25 and 40 are in the ratio:
The product of two numbers is 2880 and their GCD is 24. What is the LCM?
The least number which when divided by 5, 10, 12 and 15 leave zero remainder in each case and when divided by 18 leaves a remainder of 6 is:
Determine the total count of prime factors in the product: 217Â x 197Â x 107
Let N be the greatest number that will divide 90, 112, 134 leaving the same remainder in each case. Then sum of the digits in N is:
