the LCM of two numbers is 14 times their HCF the sum of LCM and HCF is 600 if one number is 280 then find the other number

Answer»

Hii There!!

Given that : HCF+LCM= 600, ONE NUMBER= 280

=)LET the HCF be= x

LCM= 14X

HCF+LCM= 600

X+ 14x=600

15x= 600

x= 600/15

x= 40

HCF= 40

LCM = 14x= 14× 40= 560

Since, HCF×LCM= Product of two numbers

40× 560= 280× 2nd NUMBER

2nd NUMBER= (40×560) /280

=) 40×2

= )80.


So, 2nd NUMBER =) 80.


Hope it helps:-)
