Question

The hcf of 90 and another number is 30, if the lcm of the two number is 360 find the other number

Answer 1

Answer:

The other number is 120.

Step-by-step explanation:

30×360 =90×x

x=(30×360)/90

x=120

(HCF×LCM= Product if the two numbers)

Answer 2

Answer:

Let second number is = x

we know the formula;

$l.c.m. \times first \: number = h.c.f. \times second \: number$

360 × 30 = 90 × x

1080p = 90x

x = 10800÷90

x= 120
