20 and 100.GCF is 20, and LCM is 100.
The pair of numbers whose GCF is 1 and LCM is 36 is 9 and 4. The numbers should be greater than their GCF and less than their LCM.
The GCF of 6 and 10 is 2.
12 and 396 36 and 132
The LCM of 132 and 136 is 4488. The LCM of a pair is the product of the two numbers divided by their GCF. Since the difference between the two numbers is four, we know that the GCF cannot be larger than four. Four divides evenly into both numbers, so it is the GCF. 132 * 136 / 4 = 4488.
