Given numbers are 436, 981, 610, 138

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

Apply this formula for all numbers.

Step1:

LCM(436, 981) = 3924

GCD(436, 981) = ( 436 x 981 ) / 3924

= 436 / 981

= 436

Step2:

LCM(109, 610) = 66490

GCD(109, 610) = ( 109 x 610 ) / 66490

= 109 / 610

= 109

Step3:

LCM(1, 138) = 138

GCD(1, 138) = ( 1 x 138 ) / 138

= 1 / 138

= 1

So, Greatest Common Divisor of 436, 981, 610, 138 is 1
