Given numbers are 287, 114, 786, 645

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

Apply this formula for all numbers.

Step1:

LCM(287, 114) = 32718

GCD(287, 114) = ( 287 x 114 ) / 32718

= 287 / 114

= 287

Step2:

LCM(1, 786) = 786

GCD(1, 786) = ( 1 x 786 ) / 786

= 1 / 786

= 1

Step3:

LCM(1, 645) = 645

GCD(1, 645) = ( 1 x 645 ) / 645

= 1 / 645

= 1

So, Greatest Common Divisor of 287, 114, 786, 645 is 1
