Question

find the hcf and lcm of the following.
2² * 3² * 7 ; 2²* 3* 5² ; 2² * 3³ * 5

Answer 1

Answer:

lcm=$2^{2} *3^{3}*5^{2}*7$

hcf = 2$2^{2}*3$

Answer 2

Step-by-step explanation:

1st expression = 2² × 3² × 7 = 4 × 9 × 7 = 252

2nd expression = 2² × 3 × 5² = 4 × 3 × 25 = 300

3rd expression = 2² × 3³ × 5 = 4 × 27 × 5 = 540

HCF = 4 × 3 = 12

LCM = 4 × 27 × 25 × 7 = 27 × 140 = 18900
