Given numbers are 622, 988, 780, 430

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(622, 988) = 307268

GCD(622, 988) = ( 622 x 988 ) / 307268

= 622 / 988

= 622

Step2:

LCM(2, 780) = 780

GCD(2, 780) = ( 2 x 780 ) / 780

= 2 / 780

= 2

Step3:

LCM(2, 430) = 430

GCD(2, 430) = ( 2 x 430 ) / 430

= 2 / 430

= 2

So, Greatest Common Divisor of 622, 988, 780, 430 is 2
