ఇచ్చినది:

\((49^{15} - 1) \)

ఉపయోగించిన భావన:

n సరి ధన పూర్ణాంకం అయినప్పుడు an - bn  అనేది (a + b) ద్వారా భాగించబడుతుంది.

గణన:

\((49^{15} - 1) \)

\(({(7^2)}^{15} - 1) \)

\((7^{30} - 1) \)

ఇక్కడ, 30 అనేది ధనాత్మక పూర్ణాంకం.

భావన ప్రకారం,

\((7^{30} - 1) \) (7 + 1) అంటే 8 ద్వారా భాగించబడుతుంది.

∴ 8 అనేది \((49^{15} - 1) \) భాగహారం.
