Three numbers are in the ratio 3:4:5, and their LCM is 2400; then its HCF is ___?
Let us consider the number be 3x,4xand5x
TheL.C.Mofthethreenumbersbe=60x
60x=2400
x=2400/60
x=40
Then the number be:
3x=3×40=120
4x=4×40=160
5x=5×40=200Since 40 is common.
∴ Hence the HCF of the three numbers be40.
Three number are in the ratio of 3 : 4 : 5 and their L.C.M. is 2400. What is their H.C.F?
the ratio of 2 numbers is 3:4 and their hcf is 4 .whai is thier lcm?/
