Given numbers are 645, 559, 985, 879

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

Apply this formula for all numbers.

Step1:

LCM(645, 559) = 8385

GCD(645, 559) = ( 645 x 559 ) / 8385

= 645 / 559

= 645

Step2:

LCM(43, 985) = 42355

GCD(43, 985) = ( 43 x 985 ) / 42355

= 43 / 985

= 43

Step3:

LCM(1, 879) = 879

GCD(1, 879) = ( 1 x 879 ) / 879

= 1 / 879

= 1

So, Greatest Common Divisor of 645, 559, 985, 879 is 1
