Given numbers are 408, 813, 978, 877

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

Apply this formula for all numbers.

Step1:

LCM(408, 813) = 110568

GCD(408, 813) = ( 408 x 813 ) / 110568

= 408 / 813

= 408

Step2:

LCM(3, 978) = 978

GCD(3, 978) = ( 3 x 978 ) / 978

= 3 / 978

= 3

Step3:

LCM(3, 877) = 2631

GCD(3, 877) = ( 3 x 877 ) / 2631

= 3 / 877

= 3

So, Greatest Common Divisor of 408, 813, 978, 877 is 1
