we knoe that, 1st number×2nd number=hcf×lcm
so, 6×252=6x ×7x
or 42x^2=6×252
or x^2=6×252/42
or x^2=36
or x= √36
so, x=6 answer
so, 6×252=6x ×7x
or 42x^2=6×252
or x^2=6×252/42
or x^2=36
or x= √36
so, x=6 answer

The value of x is 6.
- The HCF and LCM of numbers 6x and 7x is given as 6 and 252.
- Numbers are: 6x and 7x
HCF = 6
LCM = 252
- According to a property,
LCM × HCF = product of the numbers
6 × 252 = 6x × 7x
1512 = 42x²
x² = 36
x = 6
- The value of x is 6
- The numbers are 36 and 42.
