So far we have studied the numbers that occur very often in sentences and phrases. Whereas, now we are going to learn  big numbers in Sanskrit which are big and are rarely used except, “sahasra” which means ‘one thousand’

So let us take a look at them

English Sanskrit
one thousand (1,000) सहस्र num
by a thousand, one thousand fold; numerous, infinite साहस्र mf(ī)n
ten thousand (10,000) अयुत num
hundred thousand (100,000) लक्ष num
million (1,000,000) प्रयुत num
ten million (10,000,000) कोटि num
hundred million (100,000,000) अर्बुद num
billion (1,000,000,000) महार्बुद num
ten billion (10,000,000,000) खर्व num
hundred billion (100,000,000,000 निखर्व num

Of these words only laksa and koti have survived in English and Sanskrit, where they have transformed to’ lakhs’ and ‘crores’
