Answer:
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
=99,135,27,27/3
=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
