Given H.C.F. (306, 657) = 9, find L.C.M. (306, 657). Maths Questions, Real Numbers Questions / By mathemerize Solution : We have, H.C.F. (306, 657) = 9. We know that, Product of L.C.M and H.C.F = Product of two numbers. \(\implies\)ย L.C.M \(\times\) 9 = \(306 \times 657\) \(\implies\)ย L.C.M = \(306 \times 657 \over 9\) = 22338 Hence, L.C.M is 22338.
