B(32) = {32; 64; 96}
B(41) = {41; 82}
`B(32) = 32, 64, 96`
`B(41) = 41, 82`
Gọi số cần tìm là `x`
Có: \(\left(32;41\right)=1\)
\(\Rightarrow BCNN\left(32;41\right)=32.41=1312\)
\(\Rightarrow BC\left(32;41\right)=\left\{0;1312;2624;3936;...\right\}\)
\(mà9< x< 100\)
\(\Rightarrow x\in\varnothing\)
Gọi số cần tìm là xx
Có: (32;41)=1(32;41)=1
⇒BCNN(32;41)=32.41=1312⇒BCNN(32;41)=32.41=1312
⇒BC(32;41)={0;1312;2624;3936;...}⇒BC(32;41)={0;1312;2624;3936;...}
