用質因數分解法求H.C.F L.C.M
發問:
56= 64= H.C.F= L.C.M= .48= 72= 120= H.C.F = L.C.M=
LCM of 48, 72 and 120 should be 720, 48=2*2*2*2*3 72=2*2*2*3*3 120=2*2*2*3*5 H.C.F =2*2*2*3=24 L.C.M= 2*2*2*2*3*3*5=720, not 240 in the answer by hk chan 2007-08-14 18:38:53 補充: HCF and LCM of 56 and 64 are 8 and 448 respectively.56=2*2*2*764=2*2*2*2*2*2H.C.F = 2*2*2 = 8L.C.M = 2*2*2*2*2*2*7 = 448
