Given numbers are 820, 788, 355, 508

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

Apply this formula for all numbers.

Step1:

LCM(820, 788) = 161540

GCD(820, 788) = ( 820 x 788 ) / 161540

= 820 / 788

= 820

Step2:

LCM(4, 355) = 1420

GCD(4, 355) = ( 4 x 355 ) / 1420

= 4 / 355

= 4

Step3:

LCM(1, 508) = 508

GCD(1, 508) = ( 1 x 508 ) / 508

= 1 / 508

= 1

So, Greatest Common Divisor of 820, 788, 355, 508 is 1
