Given numbers are 982, 430, 777, 420
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(982, 430) = 211130
GCD(982, 430) = ( 982 x 430 ) / 211130
= 982 / 430
= 982
Step2:
LCM(2, 777) = 1554
GCD(2, 777) = ( 2 x 777 ) / 1554
= 2 / 777
= 2
Step3:
LCM(1, 420) = 420
GCD(1, 420) = ( 1 x 420 ) / 420
= 1 / 420
= 1
So, Greatest Common Divisor of 982, 430, 777, 420 is 1
