दिलेले आहे:

3240

संकल्पना:

जर k = ax × by , तर

a आणि b मूळ संख्या असणे आवश्यक आहे

सर्व अवयवांची बेरीज = (a0 + a1 + a2 + ….. + ax) (b0 + b1 + b2 + ….. + by)

उकल:

3240 = 23 × 34 × 51

अवयवांची बेरीज = (20 + 21 + 22 + 23) (30 + 31 + 32 + 33 + 34) (50 + 51)

⇒ (1 + 2 + 4 + 8) (1 + 3 + 9 + 27 + 81) (1 + 5)

⇒ 15 × 121 × 6

⇒ 10890

∴ आवश्यक बेरीज 10890 आहे
