6, 72 आनी 120 हांचो LCM असो आसा:
A180
B240
C720
D360
Answer & Solution
Correct answer: D. 360
1. दरेक संख्या अविभाज्यांच्या गुणनपदाच्या रुपान बरयात: 6 = 2 x 3.
2. 72 = 2^3 x 3^2 आनी 120 = 2^3 x 3 x 5.
3. एलसीएम दिसपी दर एका अविभाज्य अविभाज्यांतली सगळ्यांत चड शक्त घेता: 2^3, 3^2 आनी 5.
4. म्हणल्यार एलसीएम = 8 x 9 x 5 = 360.
5. 180 2 चो गुणनपद चुकता आनी 240 3 चो गुणनपद चुकता, देखून दोनूय 72 चो गुणनपद न्हय.
