ఇచ్చిన దత్తాంశం:

క.సా.గు దాని గ.సా.బా కి 40 రెట్లు

సంఖ్యల లబ్దం 1440

క.సా.గు దాని గ.సా.బా కి 40 రెట్లు

క.సా.గు × గ.సా.బా = సంఖ్యల లబ్దం

సాధన:

సంఖ్య యొక్క గ.సా.బా 'H' గా అనుకోనుము

⇒ క.సా.గు = 40H

ఇప్పుడు,

క.సా.గు × గ.సా.బా = సంఖ్యల ఉత్పత్తి

⇒ 40H × H = 1440

⇒ H2 = 1440/40 = 36

⇒ H = 6

∴ గ.సా.బా = 6
