Greatest common factor for 28y^7x^4u^3 and 8x^4u^5

Nataly [62]

Answer:

Step-by-step explanation:

$28y^{7} *x^{4} *u^{3} \\8x^{4} *u^{5}$

rewrite those 2 terms to better see what they have in common

$4*7 *x^{4} *u^{3} *y^{7} \\4*2*x^{4}*u^{3} *u^{2}$

because, 4*7 =28, 4*2=8, u³*u² =u^5, and multiplication is commutative

The greatest common factor is:

$4x^{4} u^{3}$
