Given numbers are 642, 111, 839, 247

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

Apply this formula for all numbers.

Step1:

LCM(642, 111) = 23754

GCD(642, 111) = ( 642 x 111 ) / 23754

= 642 / 111

= 642

Step2:

LCM(3, 839) = 2517

GCD(3, 839) = ( 3 x 839 ) / 2517

= 3 / 839

= 3

Step3:

LCM(1, 247) = 247

GCD(1, 247) = ( 1 x 247 ) / 247

= 1 / 247

= 1

So, Greatest Common Divisor of 642, 111, 839, 247 is 1
