Question

Sum of 2 number is 42 and the LCM is 72.what is that two number.

Answer 1

Answer:

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
