Question

HCF and LCM are 9 and 360. if one of the number is 45 .
find other

Answer 1

Let 2 numbers be a and b
a * b =HCF(a, b) * LCM(a, b)
45*b=9*360
b=9*360/45
b=72




Hope it helps you...

Answer 2

product of two nos. =HCF *LCM
45*x=9*360
x=
$(9 \times 360 ) \div 45$
$9 \times 8 = 72$

the other no. is 72
thank you
