Given numbers are 970, 285, 157, 556

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

Apply this formula for all numbers.

Step1:

LCM(970, 285) = 55290

GCD(970, 285) = ( 970 x 285 ) / 55290

= 970 / 285

= 970

Step2:

LCM(5, 157) = 785

GCD(5, 157) = ( 5 x 157 ) / 785

= 5 / 157

= 5

Step3:

LCM(1, 556) = 556

GCD(1, 556) = ( 1 x 556 ) / 556

= 1 / 556

= 1

So, Greatest Common Divisor of 970, 285, 157, 556 is 1
