    Nobody noticed it, but sir wrote questions 1,2,3 on right hand side bcoz when he's explaining the next 3 questions, the board won't be covered. If he wrote 1,2,3 on left side and 4,5,6 like most teachers, then while explaining 4,5,6 the first 3 questions will be covered.

    sir please calculate the lcm of 16,24,36,54? after taking 2 as common factor then they don't have common number and highest number (27) is not divisible by any number. In that situation how to calculate the lcm.

    Hello, in this case is better before to check 2 couple singularly, example 16,24= *8* ×(2×3)and his LCM = 8×2×3= *"48"* ! And the other 36,54= *18* ×(2×3)and his LCM = 18×2×3= *"108"* . And now is *enough to check the LCM* only beetwen the number *48 and 108* , continue to do the same thing it's = to *4* × (12×9)= *"432"* ! So this is the LMC of all 4 numbers. 💪💪 At Beginn you could've choose other 2 couple of number and were be the same, it's indifferent which couple of number you will choose, ok? Example 16,36 = *4* ×(4×9), LCM = 4×4×9= *144* . And 24,54= *6* (4×9), LCM= 6×4×9= *216* ! So generally LCM beetwen 144,216= *72* ×(2×3)= *432* 💪🤦‍♂️.

    Hey, to find the LCM of 90,108,280 using this method - first take 2 as common 2(45,54,140). Now find the Lcm of 45,54,140. To find it, first take common in 45 and 54, 9(5,6). Then multiply it 9×5×6. See, if the Lcm of 45, 54 has anything common with 140, 9×5×6(140). It has a 5 common. So 28 is left out, such that 9×5×6×28 = 7560
