Steps to Calculate GCD of 65, 99, 15, 16 using LCM Formula
Given numbers are 65, 99, 15, 16
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(65, 99) = 6435
GCD(65, 99) = ( 65 x 99 ) / 6435
= 65 / 99
= 65
Step2:
LCM(1, 15) = 15
GCD(1, 15) = ( 1 x 15 ) / 15
= 1 / 15
= 1
Step3:
LCM(1, 16) = 16
GCD(1, 16) = ( 1 x 16 ) / 16
= 1 / 16
= 1
So, Greatest Common Divisor of 65, 99, 15, 16 is 1
