bonjour
74 256 = 2 x 37 128
37 128 = 2 x 18 564
18 564 = 2 x 9 282
2 982 = 2 x 4 641
4 641 = 3 x 1 547
1 547 = 7 x 221
221 = 13 x 17
17 x 17 x 1
74 256 = 2 ⁴ x 3 x 7 x 13 x 17
84 942 = 2 x 42 471
42 471 = 3 x 14 157
14 157 = 3 x 4 719
4 719 = 3 x 1 573
1 573 = 11 x 143
143 = 11 x 13
13 = 13 x 1
84 942 = 2 x 3 ³ x 11 ² x 13
PPCM = 2⁴ x 3 ³ x 7 x 11 ² x 13 x 17
= 16 x 27 x 7 x 121 x 13 x 17
= 80864784
