Question

we use LCM and HCF in which types of Word problems?​

Answer 1

Answer:

Word problems on H.C.F. and L.C.M.

Therefore, least common multiple (L.C.M.) of 28, 36 and 45 = 2 × 2 × 3 × 3 × 5 × 7 = 1260.

Therefore, the required number = 1260 - 19 = 1241.

Highest common factor (H.C.F.) of 90 and 162 = 18.

Answer 2

$\huge \mathcal \red{Answer:-}$

Therefore, least common multiple (L.C.M.) of 28, 36 and 45 = 2 × 2 × 3 × 3 × 5 × 7 = 1260.

Therefore, the required number = 1260 - 19 = 1241.

Highest common factor (H.C.F.) of 90 and 162 = 18.
