GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(428, 988) = 105716
GCD(428, 988) = ( 428 x 988 ) / 105716
= 428 / 988
= 428
Step2:
LCM(4, 210) = 420
GCD(4, 210) = ( 4 x 210 ) / 420
= 4 / 210
= 4
Step3:
LCM(2, 419) = 838
GCD(2, 419) = ( 2 x 419 ) / 838
= 2 / 419
= 2
So, Greatest Common Divisor of 428, 988, 210, 419 is 1
