Given numbers are 670, 285, 975, 309

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

Apply this formula for all numbers.

Step1:

LCM(670, 285) = 38190

GCD(670, 285) = ( 670 x 285 ) / 38190

= 670 / 285

= 670

Step2:

LCM(5, 975) = 975

GCD(5, 975) = ( 5 x 975 ) / 975

= 5 / 975

= 5

Step3:

LCM(5, 309) = 1545

GCD(5, 309) = ( 5 x 309 ) / 1545

= 5 / 309

= 5

So, Greatest Common Divisor of 670, 285, 975, 309 is 1
