Given numbers are 721, 877, 533, 856

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

Apply this formula for all numbers.

Step1:

LCM(721, 877) = 632317

GCD(721, 877) = ( 721 x 877 ) / 632317

= 721 / 877

= 721

Step2:

LCM(1, 533) = 533

GCD(1, 533) = ( 1 x 533 ) / 533

= 1 / 533

= 1

Step3:

LCM(1, 856) = 856

GCD(1, 856) = ( 1 x 856 ) / 856

= 1 / 856

= 1

So, Greatest Common Divisor of 721, 877, 533, 856 is 1
