Given numbers are 642, 113, 856, 885

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

Apply this formula for all numbers.

Step1:

LCM(642, 113) = 72546

GCD(642, 113) = ( 642 x 113 ) / 72546

= 642 / 113

= 642

Step2:

LCM(1, 856) = 856

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

= 1 / 856

= 1

Step3:

LCM(1, 885) = 885

GCD(1, 885) = ( 1 x 885 ) / 885

= 1 / 885

= 1

So, Greatest Common Divisor of 642, 113, 856, 885 is 1
