Given numbers are 815, 688, 496, 842

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

Apply this formula for all numbers.

Step1:

LCM(815, 688) = 560720

GCD(815, 688) = ( 815 x 688 ) / 560720

= 815 / 688

= 815

Step2:

LCM(1, 496) = 496

GCD(1, 496) = ( 1 x 496 ) / 496

= 1 / 496

= 1

Step3:

LCM(1, 842) = 842

GCD(1, 842) = ( 1 x 842 ) / 842

= 1 / 842

= 1

So, Greatest Common Divisor of 815, 688, 496, 842 is 1
