Best ResponseYou've already chosen the best response.0Then we can divide 35 by 5 to get 7 So doing all this gives us this factor tree dw:1357595996931:dw

Best ResponseYou've already chosen the best response.0Notice how each branch multiplies to a number above it (eg: 2 and 35 below multiply to 70 above the two)

Best ResponseYou've already chosen the best response.0Then multiply them out to get 2*2*5*7 Because the twos occur twice, we can rewrite it to get \[\Large 2^2*5*7\] So in the end, \[\Large 140 = 2^2*5*7\]
