1 and 2 both do.
38 * 42 = 1,596
-4
The LCM of 38 and 42 is: 798
The factors of 42 are 1, 2, 3, 6, 7, 14, 21 and 42. The factors of 38 are 1, 2, 19 and 38. 2 is the greatest factor which divides both 38 and 42. So, the GCF of 42 and 38 is 2.
38/9 = 42/9
answer: 30 48-(0+2^1)=46 48-(2+2^2)=42 48-(2+2^3)=38 48-(2+2^4)=30
1 and 2 both do.
40 and 2. 40-38=2 and 40+2 = 42.
38 + 42 = 80
38 * 42 = 1,596
