Given numbers are 181, 645, 902, 856

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

Apply this formula for all numbers.

Step1:

LCM(181, 645) = 116745

GCD(181, 645) = ( 181 x 645 ) / 116745

= 181 / 645

= 181

Step2:

LCM(1, 902) = 902

GCD(1, 902) = ( 1 x 902 ) / 902

= 1 / 902

= 1

Step3:

LCM(1, 856) = 856

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

= 1 / 856

= 1

So, Greatest Common Divisor of 181, 645, 902, 856 is 1
