Given numbers are 280, 828, 766, 578

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

Apply this formula for all numbers.

Step1:

LCM(280, 828) = 57960

GCD(280, 828) = ( 280 x 828 ) / 57960

= 280 / 828

= 280

Step2:

LCM(4, 766) = 1532

GCD(4, 766) = ( 4 x 766 ) / 1532

= 4 / 766

= 4

Step3:

LCM(2, 578) = 578

GCD(2, 578) = ( 2 x 578 ) / 578

= 2 / 578

= 2

So, Greatest Common Divisor of 280, 828, 766, 578 is 2
