Answer 1

cmmmdc 417 , 945 = 3
cmmmc  417 945 = 3^3 x 5 x 7 x 139 = 131355

cmmmdc 3240 , 5400 = 2 ^ 3 x 3 x 5 = 1080
cmmmc 3240 , 5400 = 3 ^ 3 x 3 ^ 4 x 5 ^ 2 = 16200

cmmmdc 224 , 168 , 392  = 2 ^ 3 x 7
cmmmc 224 , 168 , 392 = 2 ^ 5 x 3 x 7 ^2

cmmmdc 48 , 192 , 576 = 2 ^4 x 3
cmmmc  48 , 192 , 576 = 2 ^ 6 x 3^ 2

cmmmdc 1008 , 1260  = 2 ^ 2 x 3 ^ 2 x 7 = 252
cmmmc 1008 , 1260 = 2 ^ 4 x 3 ^ 2 x 5 x 7 = 5040

cmmmdc 9200 , 34500  = 2 ^ 2 x 5 ^ 2 x 23 = 2300
cmmmc  9200 , 34500  = 2 ^ 4 x 3 x 5 ^ 3 x 23 = 138000

cmmmdc 27600 , 4600 = 2 ^ 3 x 5 ^ 2 x 23 = 4600
cmmmc 27600 , 4600 = 2 ^ 4 x 3 x 5 ^ 2 x 23 = 27600

cmmmdc 350 , 420 , 840 = 2 x 5 x7
cmmmc 350 , 420 , 840 = 2 ^ 3 x 3 x 5 ^ 2 x 7
