Question

Two numbers are Co-prime and their LCM is 4940. If one of the number is 65, find the other number.

Answer 1

Answer:

76

Step-by-step explanation:

Let the other number be 'k'

Since both no.s are co-primes, they have no common factor except 1

• LCM= (No. of common factors with highest power) x (All uncommon factors)
• 4940= 1 x (65 x 'k' )                                      
• 4940 = 65 k
• 76= k
• Thus, the other number is 76
