Given numbers are 305, 777, 640, 488
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(305, 777) = 236985
GCD(305, 777) = ( 305 x 777 ) / 236985
= 305 / 777
= 305
Step2:
LCM(1, 640) = 640
GCD(1, 640) = ( 1 x 640 ) / 640
= 1 / 640
= 1
Step3:
LCM(1, 488) = 488
GCD(1, 488) = ( 1 x 488 ) / 488
= 1 / 488
= 1
So, Greatest Common Divisor of 305, 777, 640, 488 is 1
