Given numbers are 842, 524, 646, 747

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

Apply this formula for all numbers.

Step1:

LCM(842, 524) = 220604

GCD(842, 524) = ( 842 x 524 ) / 220604

= 842 / 524

= 842

Step2:

LCM(2, 646) = 646

GCD(2, 646) = ( 2 x 646 ) / 646

= 2 / 646

= 2

Step3:

LCM(2, 747) = 1494

GCD(2, 747) = ( 2 x 747 ) / 1494

= 2 / 747

= 2

So, Greatest Common Divisor of 842, 524, 646, 747 is 1
