GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(781, 704) = 49984
GCD(781, 704) = ( 781 x 704 ) / 49984
= 781 / 704
= 781
Step2:
LCM(11, 255) = 2805
GCD(11, 255) = ( 11 x 255 ) / 2805
= 11 / 255
= 11
Step3:
LCM(1, 559) = 559
GCD(1, 559) = ( 1 x 559 ) / 559
= 1 / 559
= 1
So, Greatest Common Divisor of 781, 704, 255, 559 is 1
