Question

lcm of 2 numbers is 1890 and the hcf is 30.if one of them is 270,find the other

Answer 1

since we know that lcm (no 1, no 2) × hcf (no 1 , no 2 ) = no 1 × no 2

lcm = 1890

hcf = 30

no 1 = 270

let the no 2 be x

hence,

1890 × 30 = 270 × x

56700 = 270x

x = 56700/270

x=210

hence , x = no 2 = 210

VERIFICATION:

lcm (no 1, no 2) × hcf (no 1 , no 2 ) = no 1 × no 2

270 × 210 = 1890 × 30

56700=56700

Hence verified .

Hope it helps :)

Answer 2

Answer:

x=210

Step-by-step explanation:

LCM * HCF =Product of two numbers

1890 * 30   =270 * x

ie: x= 210
