Given numbers are 693, 138, 430, 974

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

Apply this formula for all numbers.

Step1:

LCM(693, 138) = 31878

GCD(693, 138) = ( 693 x 138 ) / 31878

= 693 / 138

= 693

Step2:

LCM(3, 430) = 1290

GCD(3, 430) = ( 3 x 430 ) / 1290

= 3 / 430

= 3

Step3:

LCM(1, 974) = 974

GCD(1, 974) = ( 1 x 974 ) / 974

= 1 / 974

= 1

So, Greatest Common Divisor of 693, 138, 430, 974 is 1
