Step-by-step explanation:

$\huge\mathfrak\green{ }\huge\mathfrak\pink{Answer.✫}$

$(17 \times 11 \times 2) + (17 \times 11 \times 5) (17 \times 11 \times 2)$

$=(17 \times 11) \times 2 (17 \times 11 \times 15)$

$= (17 \times 11) \times 5$

$= (17 \times 11) \times 2 + (17 \times 11) \times 5$

$= (17 \times 11) \times (2+ 5)$

$= (17 \times 11) \times 7$

$= 17 \times 11 \times 7$

$\sf more \: than \: 2 \: factors \: hence \: Composite \: number$

$Numbers having more than two factor are known as composite numbers Composite number is an integer which has atleast one factor other than 1 & number it self.$
