Given numbers are 987, 649, 515, 305
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(987, 649) = 640563
GCD(987, 649) = ( 987 x 649 ) / 640563
= 987 / 649
= 987
Step2:
LCM(1, 515) = 515
GCD(1, 515) = ( 1 x 515 ) / 515
= 1 / 515
= 1
Step3:
LCM(1, 305) = 305
GCD(1, 305) = ( 1 x 305 ) / 305
= 1 / 305
= 1
So, Greatest Common Divisor of 987, 649, 515, 305 is 1
