Question

hcf= 7 product= 294 then what is the lcm

Answer 1

Answer:

lcm×hcf=product of the two numbers

lcm × 7 = 294

lcm = 294/7

lcm = 42

Answer 2

Answer:

PLS MARK ME AS BRAINLIST

Step-by-step explanation:

HCF * LCM = Product of numbers.

So Other number = (48*294)/84

= 168 Answer.

However a cross-check shows HCF 48 (12×4) does not divide 84(12×7) and it does not divide 168 (12×2×7).

Actually, for numbers 84 & 168, HCF=84 * LCM=168.

There exist no two numbers with HCF 48 & LCM 294 & one number 84.

HCF 48 & LCM 294 means numbers are 48x & 48y and 48xy= 294.

So xy=(294/48)=147/24=49/8 =fraction & not integer.

No such x y possible with HCF 48 & LCM 294
