1. 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 1

Answer:

80

Step-by-step explanation:

Let Hcf be x

LCM = 14x

Hcf+LCM=600

x+14x=600

15x=600

x=600/15

x= 40

HCF=40,LCM=560

HCFxLCM=axb

40x560=280xb

b=40560/280

b=80
