Given numbers are 439, 666, 642, 531

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

Apply this formula for all numbers.

Step1:

LCM(439, 666) = 292374

GCD(439, 666) = ( 439 x 666 ) / 292374

= 439 / 666

= 439

Step2:

LCM(1, 642) = 642

GCD(1, 642) = ( 1 x 642 ) / 642

= 1 / 642

= 1

Step3:

LCM(1, 531) = 531

GCD(1, 531) = ( 1 x 531 ) / 531

= 1 / 531

= 1

So, Greatest Common Divisor of 439, 666, 642, 531 is 1
