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

Apply this formula for all numbers.

Step1:

LCM(398, 780) = 155220

GCD(398, 780) = ( 398 x 780 ) / 155220

= 398 / 780

= 398

Step2:

LCM(2, 862) = 862

GCD(2, 862) = ( 2 x 862 ) / 862

= 2 / 862

= 2

Step3:

LCM(2, 546) = 546

GCD(2, 546) = ( 2 x 546 ) / 546

= 2 / 546

= 2

So, Greatest Common Divisor of 398, 780, 862, 546 is 2
