Question

If hcf of a and b is 6 and product of these numbers is 1800 then what is the lcm?

Answer 1

answer

formula -

prodct of two numbers = LCM ×hcf

lets LCM consider x

1800 = x × 6

x = 1800 ÷ 6

x= 300

LCM = 300

Verification -

HCF × LCM = product of given numbets

6 × 300 = 1800

Answer 2

we know that formula that

product of two numbers=lcm X hcf

so,1800=lcm X 6

then,

lcm=1800/6

; lcm=300
