Given numbers are 138, 980, 597, 890

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

Apply this formula for all numbers.

Step1:

LCM(138, 980) = 67620

GCD(138, 980) = ( 138 x 980 ) / 67620

= 138 / 980

= 138

Step2:

LCM(2, 597) = 1194

GCD(2, 597) = ( 2 x 597 ) / 1194

= 2 / 597

= 2

Step3:

LCM(1, 890) = 890

GCD(1, 890) = ( 1 x 890 ) / 890

= 1 / 890

= 1

So, Greatest Common Divisor of 138, 980, 597, 890 is 1
