Answer»

Finding L.C.M of 2, 4, 5 and 6;

FACTORS of 2 = 2

Factors of 4 = 22

Factors of 5 = 5

Factors of 6 = 2 × 3

L.C.M(2, 4, 5, 6) = 22 × 3 × 5 = 60

Divide 3475 by 60,

⇒ 3475/60 = $(57\frac{{55}}{{60}})$ [Here 55 represent the remainder which need to make 0 for that,60 - 55 need to do. Answer of subtraction is REQUIRED answer which need to add in 3475]

∴ Number need to add = 60 – 55 = 5
