the lcm of two number is 14times than their hcf. the sum of lcm and hcf is 600 . if one number is 280 . Then find other number .

For 10th class

answer fast friends plz

sujit21 Good afternoon dear....

GIVEN: HCF+LCM= 600, ONE NUMBER= 280.

Let the HCF= X

LCM= 14X

HCF+lcm =600

thn ,

X+ 14X=600
15X= 600
X= 600/15
X= 40.

HCF= 40
LCM = 14X= 14× 40= 560.

HCF×LCM= 1ST NUMBER × 2ND NUMBER.
2ND NUMBER= (40×560) /280
2ND NUMBER= 40×2
= 80 .

I hope it's helps u alot.

Thanku.....

sujit21 thank u

singhbhupendrap6ux6y Lcm = 14 hcf , lcm +hcf = 600 , then put the value of lcm in 2 equation then 14 hcf + hcf = 600 , 15hcf =600 , hcf = 40 , hcf × lcm = one no. × other no., and lcm= 14 hcf = 14× 40=560 ,560×40= 280×other no. , other no.= 80
