Given numbers are 392, 528, 921, 680

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

Apply this formula for all numbers.

Step1:

LCM(392, 528) = 25872

GCD(392, 528) = ( 392 x 528 ) / 25872

= 392 / 528

= 392

Step2:

LCM(8, 921) = 7368

GCD(8, 921) = ( 8 x 921 ) / 7368

= 8 / 921

= 8

Step3:

LCM(1, 680) = 680

GCD(1, 680) = ( 1 x 680 ) / 680

= 1 / 680

= 1

So, Greatest Common Divisor of 392, 528, 921, 680 is 1
