Given numbers are 642, 362, 145, 839

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

Apply this formula for all numbers.

Step1:

LCM(642, 362) = 116202

GCD(642, 362) = ( 642 x 362 ) / 116202

= 642 / 362

= 642

Step2:

LCM(2, 145) = 290

GCD(2, 145) = ( 2 x 145 ) / 290

= 2 / 145

= 2

Step3:

LCM(1, 839) = 839

GCD(1, 839) = ( 1 x 839 ) / 839

= 1 / 839

= 1

So, Greatest Common Divisor of 642, 362, 145, 839 is 1
