\(44442222=44440000+2222=4.1111.10^4+2.1111\)
\(4.1111.10^4+2.1111=4.1111.\left(9.1111+1\right)+2.1111\)
\(4.1111.\left(9.1111+1\right)+2.1111=1111.\left(36.1111+4\right)+2.1111\)
\(1111.\left(36.1111+4\right)+2.1111=1111.\left(36.1111+4+2\right)\)
\(1111.\left(36.1111+4+2\right)=6.1111.\left(6.1111+1\right)\)
\(6.1111.\left(6.1111+1\right)=6666.6667\left(DPCM\right)\)
