1 x 84, 2 x 42, 3 x 28, 4 x 21, 6 x 14, 7 x 12 = 84
The GCF is 1.
4,123,569,635,463,424,546 plus Justin Bieber. ^_^
It is 7*(12 + 4).
The LCM is: 84
7x + 8 = 84 Subtract 8 from bith sides: 7x = 76 Divide both sides by 7: x = 76/7 = 10.8571428...
567 + 193 + 84 = 844
84 + 16 = 100
96
77
y=84-72=12 z=84-52=32 x=84-12-32=40
405
17+67= 84
42 + 42 = 84
64
3x + 4x = 847x = 84divide both sides by 7x = 12
79 + k = 84 84 - 79 = k k = 5
