Answer :

GCF of the two numbers is 10
This is the largest integer that they can both be divided by and still obtain an integer as a result.

390/10 = 39
250/10 = 25

LCM of the two numbers is 9750
This is the smallest number that can be obtained by multiplication of an integer an obtain an integer as a result.

390*25 = 9750
250*39 = 9750


the gcf of the no is 10 because this is highest factor and if we will divide 390 by  10 it will be 39 and  with 250 by 10 will be 25

the lcm of the 390 and 250 is  9750 because it is the smallest number whicis multiplied by the  number

390*25=9750

250*39=9750.....
