Step 4 solve the problem
1.90 = 1 time; 90 = 2 times; 45 = 3 times; 30 = 5 times; 18 = 6 times; 15 = 9 times; There are six kinds of 10, namely 1 and 90, 2 and 45, 3 and 30, 5 and 18, 6 and 15, 9 and 10.
2.336 = 2 times; 2 times; 2 times; 2 times; 3 times; 7 = 6 times; 7 times; eight
6+7+8=2 1
3.( 1)260 = 2 times; 2 times; 5 times; 13 so these two numbers are 4 and 65.
(2)420 = 2 times; 2 times; 3 times; 5 times; 7 So these two numbers are 4 and 105, 12 and 35, 15 and 28, 20 and 2 1.
leave out
6.( 1)48 = 2 times; 2 times; 2 times; 2 times; 3 So A=3 and B= 12.
