Given numbers are 186, 612, 974, 780

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

Apply this formula for all numbers.

Step1:

LCM(186, 612) = 18972

GCD(186, 612) = ( 186 x 612 ) / 18972

= 186 / 612

= 186

Step2:

LCM(6, 974) = 2922

GCD(6, 974) = ( 6 x 974 ) / 2922

= 6 / 974

= 6

Step3:

LCM(2, 780) = 780

GCD(2, 780) = ( 2 x 780 ) / 780

= 2 / 780

= 2

So, Greatest Common Divisor of 186, 612, 974, 780 is 2
