Given numbers are 986, 146, 80, 545

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

Apply this formula for all numbers.

Step1:

LCM(986, 146) = 71978

GCD(986, 146) = ( 986 x 146 ) / 71978

= 986 / 146

= 986

Step2:

LCM(2, 80) = 80

GCD(2, 80) = ( 2 x 80 ) / 80

= 2 / 80

= 2

Step3:

LCM(2, 545) = 1090

GCD(2, 545) = ( 2 x 545 ) / 1090

= 2 / 545

= 2

So, Greatest Common Divisor of 986, 146, 80, 545 is 1
