Question

The HCF and LCM of two numbers are 13 and 1989 respectively. If one number is 117, find the other.

Answer 1

Answer:

The other number is 221..

Step by step:

HCF×LCM=product of two numbers

Let other number be "x",

117x=13×1989

117x=25857

x=25857/117

x=221....

I hope it helps you...

${\bold{\huge{\pink{\underline{\green{G}\purple{iv}\orange{en}\red{:-}}}}}}$

• $\bf\:HCF=\:13$

• $\bf\:LCM=\:1989$

• $\bf\:One\: Number=117$

${\bold{\huge{\pink{\underline{\pink{F}\purple{in}\blue{d}\red{:-}}}}}}$

• $\bf\:Other\: Number=?$

${\bold{\huge{\pink{\underline{\red{So}\purple{lut}\green{ion}\orange{:-}}}}}}$

Let the other number be x

$\bf\:By\:Using\: Formula:-$

$\bf\:We\:know\:that,$

Product of HCF and LCM = Product of two numbers.

$\bf\:13\times\:1989=117\times\:x$

$\bf\:25857=117x$

$\bf\:x=\dfrac{25857}{117}$

$\bf\:x=221$

Hence,other number will be 221
