GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(628, 544) = 85408
GCD(628, 544) = ( 628 x 544 ) / 85408
= 628 / 544
= 628
Step2:
LCM(4, 406) = 812
GCD(4, 406) = ( 4 x 406 ) / 812
= 4 / 406
= 4
Step3:
LCM(2, 289) = 578
GCD(2, 289) = ( 2 x 289 ) / 578
= 2 / 289
= 2
So, Greatest Common Divisor of 628, 544, 406, 289 is 1
