Question

find the two numbers whose sum is 42 and lcm 72

Answer 1

let one number be x then another one will be 42-x
since their LCM are 72 then they completely divide it
let's check out the prime factors of 72 i.e. 2*2*2*3*3
now check out the combination of prime factors which is smaller than 42 i.e 24
so the two numbers formed are x=24 and 42-x=18
SO TWO NUMBERS ARE 18 AND 24..

Answer 2

Answer:

24 and 18

Step-by-step explanation:

Factors of 72

1*72 ; 1+72=73

2*36 ; 2+36=38

3*24 ; 24+3=27

4*18 ; 18+4=22

6*12 ; 12+6=18

8*9 ; 8+9=17

Here , 24+18=42

And the LCM of 24 and 18
