Tentukan KPK dan FPB dari: A. 12a²b dan 15abc B. 24p²q²r,32pq²s,dan 72q³r²s³ Tolong pakai cara ya!! :)

a) 12a²b = 2² × 3 × a² × b
15abc = 3 × 5 × a × b × c
kpk = 2² × 3 × 5 × a² × b × c = 60a²bc
fpb = 3 × a × b = 3ab

b) 24p²q²r = 2³ × 3 × p² × q² × r
32pq²s = 2^5 × p × q² × s
72q³r²s³ = 2³ × 3² × q³ × r² × s³
kpk = 2^5 × 3² × p² × q³ × r² × s³
= 288p²q³r²s³
fpb = 2³ × q² = 8q²

a)
12a²b = 2² x 3 x a² x b
15abc = 3 x 5 x a x b x c
maka,
KPK
= 2² x 3 x 5 x a² x b x c
= 4x3x5 a²bc
= 60 a²bc

FPB
= 3 x a x b
= 3ab


b)
24p²q²r = 2^3 x 3 x p² x q² x r
32pq²s = 2^5 x p x q² x s
72q^3 r² s^3 = 2^3 x 3² x q^3 x r² x s^3
maka,
KPK
= 2^5 x 3² x p² x q^3 x r² x s^3
= 32 x 9 x p²q^3 r² s^3
= 288 p²q^3 r² s^3

FPB
= 2^3 x q²
= 8q²
