By proportionality, for any number

, if T is multiplied by

then the same goes for M.
a) M has been multiplied by

hence


b) T has been divided by

hence

Prime factors of 42: 2x7x3
prime factors of 126: 2x3x3x7
prime factors of 210: 7x3x5x2
now we multiply all the factors that they all have in common: 2x3x7 which is 42. So the highest common factor is 42
