HCF and LCM of 404 and 96 and verify that HCF ×LCM = product of two no |
| Answer» Prime factorisation of 404 and 96 is:404 = 2\xa0{tex}\\times{/tex}\xa02\xa0{tex}\\times{/tex}\xa0101404 = 22\xa0{tex}\\times{/tex}\xa010196 = 2\xa0{tex}\\times{/tex}\xa02\xa0{tex}\\times{/tex}\xa02\xa0{tex}\\times{/tex}\xa02\xa0{tex}\\times{/tex}\xa02\xa0{tex}\\times{/tex}\xa0396 = 25\xa0{tex}\\times{/tex}\xa03{tex}\\therefore{/tex}\xa0HCF(404,96 )= 22 = 4LCM(404, 96 ) = 101\xa0{tex}\\times{/tex}\xa025\xa0{tex}\\times{/tex}\xa03LCM( 404, 96) = 9696now we have to verify that,HCF(404, 96)\xa0{tex}\\times{/tex}LCM(404, 96) = 404{tex}\\times{/tex}96Hence,LHS = HCF\xa0{tex}\\times{/tex}\xa0LCM = 4\xa0{tex}\\times{/tex}\xa09696 = 38784\xa0RHS= Product of numbers =404\xa0{tex}\\times{/tex}\xa096 = 38784Since, LHS=RHSi.e. HCF\xa0{tex}\\times{/tex}\xa0LCM = Product of 404 and 96.hence verified | |

Express the hcf of 963 and 657 as 963x and 65 7y where x and y are integers |
| Answer» By applying Euclid’s division lemma,{tex}963 = 657\\times 1 + 306.{/tex}Since remainder ≠ 0, apply division lemma on divisor 657 and remainder 306{tex}657 = 306\\times 2 + 45.{/tex}Since remainder ≠ 0, apply division lemma on divisor 306 and remainder 45{tex}306 = 45\\times 6 + 36.{/tex}Since remainder ≠ 0, apply division lemma on divisor 45 and remainder 36{tex}45 = 36\\times 1 + 9.{/tex}Since remainder ≠ 0, apply division lemma on divisor 36 and remainder 9{tex}36 = 9 \\times\xa04 + 0.{/tex}Therefore, {tex}H.C.F. = 9.{/tex}HCF of 2 numbers can be expressed as the linear combination of the numbers{tex}\\Rightarrow {/tex} 9 = 45 - 36 {tex}\\times{/tex}\xa01= {tex}45 - [306 - 45 \\times\xa06] \\times\xa01 = 45 - 306\\times 1 + 45\\times 6{/tex}= {tex}45 \\times\xa07 - 306\\times 1 = [657 -306\\times 2]\\times 7 - 306 × 1{/tex}= {tex}657 \\times\xa07 - 306 \\times\xa014 - 306 × 1{/tex}= {tex}657\\times 7 - 306\\times 15{/tex}= {tex}657\\times 7 - [963 - 657 × 1] \\times\xa015{/tex}= 657 {tex}\\times{/tex}\xa07 - 963 {tex}\\times{/tex}\xa015 + 657 {tex}\\times{/tex}\xa015= 657 {tex}\\times{/tex}\xa022 - 963 {tex}\\times{/tex}\xa015.Hence, obtained. | |
