Question

IF HCF(253,440)=1 and LCM (253,440) =253R, find the value of R​

Answer 1

HCF (253,440)=1

LCM (253,440)=253R

HCF×LCM=AB

1×253R=253×440

R=440

Answer 2

WE KNOW THAT,

LCM×HCF=FIRST NUMBER × SECOND NUMBER

SO THAT,

1×253R= 253×440

253R=253×440

R=(253×440)/253

R=440 is the answer

I hope that helps you
