Given numbers are 126, 728, 620, 816

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

Apply this formula for all numbers.

Step1:

LCM(126, 728) = 6552

GCD(126, 728) = ( 126 x 728 ) / 6552

= 126 / 728

= 126

Step2:

LCM(14, 620) = 4340

GCD(14, 620) = ( 14 x 620 ) / 4340

= 14 / 620

= 14

Step3:

LCM(2, 816) = 816

GCD(2, 816) = ( 2 x 816 ) / 816

= 2 / 816

= 2

So, Greatest Common Divisor of 126, 728, 620, 816 is 2
