2bm - 15bn + 4am - 30an
= 4am + 2bm - 30an - 15bn
= 2m( 2a + b ) - 15n( 2a + b )
= ( 2a + b )( 2m - 15n )
或者
= 4am - 30an + 2bm - 15bn
= 2a( 2m - 15n ) + b( 2m - 15n )
= ( 2a + b )( 2m - 15n )

2bm - 15bn + 4am - 30an
= 4am + 2bm - 30an - 15bn
= 2m( 2a + b ) - 15n( 2a + b )
= ( 2a + b )( 2m - 15n )
或者
= 4am - 30an + 2bm - 15bn
= 2a( 2m - 15n ) + b( 2m - 15n )
= ( 2a + b )( 2m - 15n )
