Given numbers are 758, 780, 842, 487

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

Apply this formula for all numbers.

Step1:

LCM(758, 780) = 295620

GCD(758, 780) = ( 758 x 780 ) / 295620

= 758 / 780

= 758

Step2:

LCM(2, 842) = 842

GCD(2, 842) = ( 2 x 842 ) / 842

= 2 / 842

= 2

Step3:

LCM(2, 487) = 974

GCD(2, 487) = ( 2 x 487 ) / 974

= 2 / 487

= 2

So, Greatest Common Divisor of 758, 780, 842, 487 is 1
