GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(542, 440) = 119240
GCD(542, 440) = ( 542 x 440 ) / 119240
= 542 / 440
= 542
Step2:
LCM(2, 340) = 340
GCD(2, 340) = ( 2 x 340 ) / 340
= 2 / 340
= 2
Step3:
LCM(2, 406) = 406
GCD(2, 406) = ( 2 x 406 ) / 406
= 2 / 406
= 2
So, Greatest Common Divisor of 542, 440, 340, 406 is 2
