Given numbers are 987, 349, 642, 194

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

Apply this formula for all numbers.

Step1:

LCM(987, 349) = 344463

GCD(987, 349) = ( 987 x 349 ) / 344463

= 987 / 349

= 987

Step2:

LCM(1, 642) = 642

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

= 1 / 642

= 1

Step3:

LCM(1, 194) = 194

GCD(1, 194) = ( 1 x 194 ) / 194

= 1 / 194

= 1

So, Greatest Common Divisor of 987, 349, 642, 194 is 1
