Q.1 Solve the following:-
1) If first Number is 100 and second Number is 150,HCF 25 find LCM
2) If HCF is 30 and LCM is 210 Find the product of 2 Numbers
3) If first Number is 66 and second Number is 72,LCM is 198 find HCF
4) If the product of 2 Numbers is 132,HCF is 56 find LCM
5) If second Number is 81, HCF is 27 and LCM is 350 find the first Number​

Answer 1

Answer:

1. lcm * hcf = product of two numbers

lcm = 100* 150 / 25 = 600

Step-by-step explanation:

2. product of two nos = 30 * 210 = 6300

3. hcf = 66 * 72/198 = 24

4. lcm = 132/56

5. first number = 27* 350/ 81

= 350/ 3
