Answer 1

Answer:

LCM = 5940

Step-by-step explanation:

Prime factorisation of 1624 = 2 × 2 × 2 × 7 × 29

Prime factorisation of 522 = 2 × 3 × 3 × 29

Prime factorisation of 1276 = 2 × 2 × 29 × 11

HCF of 1624 , 522 , 1276 = 2 × 29 = 58

LCM of 198 , 135 , 108 and 54 .

=198,135,108,54/2

=99,135,54,27/2

=33,45,9,9/3

=11,15,3,3/3

=11,5,1,1/5

=11,1,1,1/11

=1,1,1,1

= L.C.M of

198,135,108,54=2*2*3*3*3*5*11=5940
