Answer 1

Answer:

hey here is your solution

pls mark it as brainliest

I have given only few answers

rest you do by yourself after interpreting the method

Step-by-step explanation:

so basically LCM is the number which is less common multiple of more than one number

so here

1.42,77

here 42 is divisible by 7,6,14,2,3,42

77 is divisible by 11,7,77

so hence LCM is 7

2.144,180,

so here 144 is divisible by ,2,3,4,6,8,9,12,16,24,18,36,48,72,144

180 is divisible by ,2,3,4,5,6,9,10,12,18,20,30,60,90,180

so here common factors are 2,3,4,6,9,12

but 2 being the smallest number

LCM of 144 and 180 is 2
