Question

The LCM and HCF of three numbers are 525 and 25 respectively. If the two numbers are 25 and 105, then find the third number?

Answer 1

HCF is the highest common factor i.e., If d is the common factor of a , b and c, Then d divides a , b and c. Here 25 is given as the HCF of 25,105 and the third number. So 25 must divide 25 and 105. But 25 does not divide 105. 105 = 5*3*7.
