Given numbers are 655, 488, 660, 605
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(655, 488) = 319640
GCD(655, 488) = ( 655 x 488 ) / 319640
= 655 / 488
= 655
Step2:
LCM(1, 660) = 660
GCD(1, 660) = ( 1 x 660 ) / 660
= 1 / 660
= 1
Step3:
LCM(1, 605) = 605
GCD(1, 605) = ( 1 x 605 ) / 605
= 1 / 605
= 1
So, Greatest Common Divisor of 655, 488, 660, 605 is 1
