Question

hcf of 120 150 and 180 ​

Answer 1

Answer:

Step-by-step explanation:

120 = 5 x 2 x 2 x 2 x 3

150 = 5 x 2 x 3 x 5

180 = 5 x 2 x 2 x 3 x 3

So, in common, we have one 2 (limited by 150), one 5, (limited by 120 and 180), and one 3 (limited by120 and 150)

2 x 3 x 5 = 6 x 5 = 30 <<< gcf

Answer 2

Answer: 30

Step-by-step explanation:

Prime factorization method

120 = 10 x 12 = 2 x 2 x 2 x 3 x 5

150 = 10 x 15 = 2 x 3 x 5 x 5

180 = 10 x 18 = 2 x 2 x 3 x 3 x 5

H.C.F (120,150,180) = 2 x 3 x 5 = 30
