MARK MY ANSWER AS BRAINLIEST PLEASE

Step-by-step explanation:

13. 600.

The least common multiple of 120 and 300 is 600 because 600 is the smallest number that is divisible by 120 and 300.

10.HCF of (137−2),(182−2) and (422−2).

= HCF of (135,180,420) =15.

15. LCM of 1566 & 2030= 54810

To find, HCF=?

So...We know that,

LCM ×HCF= PRODUCT of two nos.

54810x HCF =1566 x 2030

HCF= 3178980÷54810

HCF=58

HENCE ,HCF =58
