The HCF of two numbers is 21 and their LCM is 693. If

Q: Answer-The HCF of two numbers is 21 and their LCM is 693. If one of the numbers is 63, find the other numbe...

For two numbers a and b a b HCF LCM Let other number x. 63 x 21 693 Compute RHS 21693 21700 7 14,700 147 14,553 So x 14,553 63 63200 12,600 Remaining 1,953 6330 1,890 Remaining 63 So x 200 30 1 231 Check 231 21 11, So 231 is a multiple of the HCF.

one of the numbers is 63, find the other number and verify that it is a multiple of the HCF.

A 335

B 231

C 169

D 273
