Given numbers are 821, 864, 664, 881

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

Apply this formula for all numbers.

Step1:

LCM(821, 864) = 709344

GCD(821, 864) = ( 821 x 864 ) / 709344

= 821 / 864

= 821

Step2:

LCM(1, 664) = 664

GCD(1, 664) = ( 1 x 664 ) / 664

= 1 / 664

= 1

Step3:

LCM(1, 881) = 881

GCD(1, 881) = ( 1 x 881 ) / 881

= 1 / 881

= 1

So, Greatest Common Divisor of 821, 864, 664, 881 is 1
