Given numbers are 945, 678, 598, 691

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

Apply this formula for all numbers.

Step1:

LCM(945, 678) = 213570

GCD(945, 678) = ( 945 x 678 ) / 213570

= 945 / 678

= 945

Step2:

LCM(3, 598) = 1794

GCD(3, 598) = ( 3 x 598 ) / 1794

= 3 / 598

= 3

Step3:

LCM(1, 691) = 691

GCD(1, 691) = ( 1 x 691 ) / 691

= 1 / 691

= 1

So, Greatest Common Divisor of 945, 678, 598, 691 is 1
