Given numbers are 645, 625, 985, 116

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

Apply this formula for all numbers.

Step1:

LCM(645, 625) = 80625

GCD(645, 625) = ( 645 x 625 ) / 80625

= 645 / 625

= 645

Step2:

LCM(5, 985) = 985

GCD(5, 985) = ( 5 x 985 ) / 985

= 5 / 985

= 5

Step3:

LCM(5, 116) = 580

GCD(5, 116) = ( 5 x 116 ) / 580

= 5 / 116

= 5

So, Greatest Common Divisor of 645, 625, 985, 116 is 1
