GCF must divide both numbers. So,

2x5x7x7 (c)

#2

LCM must be a multiple of both numbers. So,

2x3x3x5x5x5x7x7 (d)

(e) is also a multiple, but not the LEAST multiple

**Steve**, Sunday, October 6, 2013 at 7:29pm2x2x5x7x7 = 2x5x7x7 x 2

2x5x5x7x7 = 2x5x7x7 x 5

There's no number which divides both 5 and 7, so we've reached the greatest factor of both values.
