Bro please mark as brilliant and follow me ...
for my efforts
Step-by-step explanation:
27 is a composite number. 27 = 1 x 27, or 3 x 9. Factors of 27: 1, 3, 9, 27
(a) 24 = 1 x 24 = 2 x 12 = 3 x 8 = 4 x 6 = 6 x 4
ˆ´ Factors of 24= 1,2,3,4,6,12,24
(b) 15=1 x 15 = 3 x 5 = 5 x 3
ˆ´ Factors of 15 = 1, 3, 5, 15
(c) 21=1 x 21 = 3 x 7 = 7 x 3
ˆ´ Factors of 21 = 1, 3, 7, 21
(d) 27= 1 x 27 = 3 x 9 = 9 x3
ˆ´ Factors of 27 = 1, 3, 9, 27
(e) 12 = 1 x 12 = 2 x 6 = 3 x 4 = 4 x 3
ˆ´ Factors of 12 = 1, 2, 3, 4, 6, 12
(f) 20=1 x 20 = 2 x 10 = 4 x 5 = 5 x 4
ˆ´ Factors of 20 = 1, 2, 4, 5, 10, 20
(g) 18=1 x 18 = 2 x 9 = 3 x
ˆ´Factors of 18 = 1, 2, 3, 6, 9, 18
(h) 23=1 x 23
ˆ´Factors of 23 = 1, 23
(i) 36== 1 x 36 = 2 x 18 = 3 x 12 = 4 x 9 = 6 x6
ˆ´ Factors of 36 = 1, 2, 3, 4, 6, 9, 12, 18, 36
