Given numbers are 156, 856, 824, 561

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

Apply this formula for all numbers.

Step1:

LCM(156, 856) = 33384

GCD(156, 856) = ( 156 x 856 ) / 33384

= 156 / 856

= 156

Step2:

LCM(4, 824) = 824

GCD(4, 824) = ( 4 x 824 ) / 824

= 4 / 824

= 4

Step3:

LCM(4, 561) = 2244

GCD(4, 561) = ( 4 x 561 ) / 2244

= 4 / 561

= 4

So, Greatest Common Divisor of 156, 856, 824, 561 is 1
