Given numbers are 342, 987, 857, 603

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

Apply this formula for all numbers.

Step1:

LCM(342, 987) = 112518

GCD(342, 987) = ( 342 x 987 ) / 112518

= 342 / 987

= 342

Step2:

LCM(3, 857) = 2571

GCD(3, 857) = ( 3 x 857 ) / 2571

= 3 / 857

= 3

Step3:

LCM(1, 603) = 603

GCD(1, 603) = ( 1 x 603 ) / 603

= 1 / 603

= 1

So, Greatest Common Divisor of 342, 987, 857, 603 is 1
