The greatest common factor of 290 and 660 is 10. What is their least common factor? Correct Answer 19140

Given:

Numbers are 290, 660.

Greatest Common Factor means HCF (290, 660) = 10.

Concept used:

A × B = LCM (A,B) × HDF (A,B)

Calculation:

Least Common Multiple or LCM = (290 × 660) ÷ 10 = 19140

∴ The least common multiple of 290 & 660 is 19140.
