Given numbers are 220, 558, 428, 622
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(220, 558) = 61380
GCD(220, 558) = ( 220 x 558 ) / 61380
= 220 / 558
= 220
Step2:
LCM(2, 428) = 428
GCD(2, 428) = ( 2 x 428 ) / 428
= 2 / 428
= 2
Step3:
LCM(2, 622) = 622
GCD(2, 622) = ( 2 x 622 ) / 622
= 2 / 622
= 2
So, Greatest Common Divisor of 220, 558, 428, 622 is 2
