Answer:
a. 90 = LCM 3 = HCF
b. 56 = LCM, 8 = HCF
c. 72 = LCM, 6 = HCF
Step-by-step explanation:
a. I... don't know how to explain this one.
b. LCM = 56 is divisible by 8 so it is a multiple of 8. Since every no. is a multiple of itself, 56 is also the lowest multiple of 56. HCF = Since 8 does not have any factor greater than itself, and 8 is also a factor of 56, it is the HCF
c. LCM = 72 is divisible by 6 so it is a multiple of 6. Since every no. is a multiple of itself, 72 is also the lowest multiple of 72. HCF = Since 6 does not have any factor greater than itself, and 6 is also a factor of 72, it is the HCF.
I know I'm not a great teacher but I tried my best to explain
