[21-11-2020]Lecture 4: HCF and LCM, Concept and questions based on HCF and LCM asked in previous years CSAT
The smallest 4 digit number is 1000?
Yes….999 is largest 3 digit no.
I think mam has taken 10000 instead of 1000
Have taken 1000 only, its kind of writo….when 1000 is divided by 60, remainder comes as 40
(60*16=960)…..
Namaste mam, mam which book do you suggest to practise questions,
Mam aapne 20min. Me 20 ka multiple 45 but ye 22*5 ho skta h, or 2 common to 150min. Answer. Please correct me if I am wrong
2 only 20 k factors me aayega…25 =5×5
20=2×2×5, 15=3×5
One 5 is common in all
Banki koi aisa nhmber nahi hai jo common ho…
So LCM =5×5×2×3=300
Agar aap 150 dekhte hain to 150 is not divisible by 20. So LCM 150 is not correct
Yes I learnt a lot of things thank you so much mam
