Question

find the hcf and lcm of 28 and 40 and verify that hcf × lcm = product of the for this year​

Answer 1

H.C.F is

40=28×1+12

28=12×2+4

12=4×2+0

H.C.F is 4

L.C.M

28=2×14

=2×2×7

40=2×20

=2×2×10

=2×2×2×5

L.C.M=2×2×7×2×5

=280

now proving

280×4=28×40

1120=1120

L.H.S=R.H.S hence proof
