Given numbers are 855, 455, 743, 802

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

Apply this formula for all numbers.

Step1:

LCM(855, 455) = 77805

GCD(855, 455) = ( 855 x 455 ) / 77805

= 855 / 455

= 855

Step2:

LCM(5, 743) = 3715

GCD(5, 743) = ( 5 x 743 ) / 3715

= 5 / 743

= 5

Step3:

LCM(1, 802) = 802

GCD(1, 802) = ( 1 x 802 ) / 802

= 1 / 802

= 1

So, Greatest Common Divisor of 855, 455, 743, 802 is 1
