Given numbers are 487, 136, 638, 559
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(487, 136) = 66232
GCD(487, 136) = ( 487 x 136 ) / 66232
= 487 / 136
= 487
Step2:
LCM(1, 638) = 638
GCD(1, 638) = ( 1 x 638 ) / 638
= 1 / 638
= 1
Step3:
LCM(1, 559) = 559
GCD(1, 559) = ( 1 x 559 ) / 559
= 1 / 559
= 1
So, Greatest Common Divisor of 487, 136, 638, 559 is 1
