Given numbers are 630, 186, 780, 838

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

Apply this formula for all numbers.

Step1:

LCM(630, 186) = 19530

GCD(630, 186) = ( 630 x 186 ) / 19530

= 630 / 186

= 630

Step2:

LCM(6, 780) = 780

GCD(6, 780) = ( 6 x 780 ) / 780

= 6 / 780

= 6

Step3:

LCM(6, 838) = 2514

GCD(6, 838) = ( 6 x 838 ) / 2514

= 6 / 838

= 6

So, Greatest Common Divisor of 630, 186, 780, 838 is 2
