GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(776, 390) = 151320
GCD(776, 390) = ( 776 x 390 ) / 151320
= 776 / 390
= 776
Step2:
LCM(2, 256) = 256
GCD(2, 256) = ( 2 x 256 ) / 256
= 2 / 256
= 2
Step3:
LCM(2, 422) = 422
GCD(2, 422) = ( 2 x 422 ) / 422
= 2 / 422
= 2
So, Greatest Common Divisor of 776, 390, 256, 422 is 2
