207???
First ask yourself , will it divide by '2'. The answer is no , because it is not an even number.
Then try '3'
207/3 = 69 . This gives a whole number answer. So the two numbers are 3, & 69.
NB with any question like this, ask yourself #1 is it even? If so it will divide by '2'.
#2 Does it end in '0' or '5', then it will divide by '5'.
#3 Do the digits add to '9'. If so it will divide by '9' . In this case '207' ; 2 + 0 + 7 = 9 So 207 will; divide by '9'
#4 Then try '3'
#5 Finally, try '7' .
NB Ignore 4, 6, & 8 .they are even and will divide again by '2'.
