Given numbers are 428, 981, 524, 137

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

Apply this formula for all numbers.

Step1:

LCM(428, 981) = 419868

GCD(428, 981) = ( 428 x 981 ) / 419868

= 428 / 981

= 428

Step2:

LCM(1, 524) = 524

GCD(1, 524) = ( 1 x 524 ) / 524

= 1 / 524

= 1

Step3:

LCM(1, 137) = 137

GCD(1, 137) = ( 1 x 137 ) / 137

= 1 / 137

= 1

So, Greatest Common Divisor of 428, 981, 524, 137 is 1
