Expert Answer

For the all the above questions, we use the formula H.C.F x L.C.M. = Product of numbers

$a right parenthesis space 16 space cross times space L C M space equals space 32 space cross times space 48 rightwards double arrow L C M space equals space fraction numerator 32 space cross times 48 over denominator 16 end fraction equals space 96 b right parenthesis space H C F space cross times 140 space equals space 20 space cross times space 28 rightwards double arrow H C F space equals space fraction numerator 20 space x space 28 over denominator 140 end fraction space equals space 4 c right parenthesis space 15 space cross times space 180 space equals space 60 space x space 2 n d space n u m b e r rightwards double arrow fraction numerator 15 space cross times space 180 over denominator 60 end fraction space equals space 2 n d space n u m b e r rightwards double arrow 2 n d space n u m b e r space equals space 45 d right parenthesis space 28 space cross times space 168 space equals space 1 s t space n u m b e r space cross times space 84 rightwards double arrow fraction numerator 28 space cross times space 168 over denominator 84 end fraction space equals space 1 s t space n u m b e r rightwards double arrow 1 s t space n u m b e r space equals space 56 e right parenthesis space 44 space cross times space L C M space equals space 44 space cross times space 88 rightwards double arrow space L C M space equals space 88$
