Given numbers are 556, 988, 42, 153

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

Apply this formula for all numbers.

Step1:

LCM(556, 988) = 137332

GCD(556, 988) = ( 556 x 988 ) / 137332

= 556 / 988

= 556

Step2:

LCM(4, 42) = 84

GCD(4, 42) = ( 4 x 42 ) / 84

= 4 / 42

= 4

Step3:

LCM(2, 153) = 306

GCD(2, 153) = ( 2 x 153 ) / 306

= 2 / 153

= 2

So, Greatest Common Divisor of 556, 988, 42, 153 is 1
