Given:
LCM of two numbers is 28 times of their HCF.
⟶ LCM = 28HCF -- equation (1)
Sum of their LCM and HCF = 1740
⟶ LCM + HCF = 1740
⟶ 28HCF + HCF = 1740
[ From equation (1) ]
⟶ 29HCF = 1740
⟶ HCF = 1740/29
⟶ HCF = 60
Substitute the value of HCF in equation (1).
⟶ LCM = 28(60)
⟶ LCM = 1680
Also given that,
One of the numbers = 240.
So, Let the other number be x.
We know that,
Product of two numbers = HCF × LCM
⟶ (240)(x) = (60)(1680)
⟶ x = (60)(1680) / 240
⟶ x = 420
