Given numbers are 523, 656, 891, 658

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

Apply this formula for all numbers.

Step1:

LCM(523, 656) = 343088

GCD(523, 656) = ( 523 x 656 ) / 343088

= 523 / 656

= 523

Step2:

LCM(1, 891) = 891

GCD(1, 891) = ( 1 x 891 ) / 891

= 1 / 891

= 1

Step3:

LCM(1, 658) = 658

GCD(1, 658) = ( 1 x 658 ) / 658

= 1 / 658

= 1

So, Greatest Common Divisor of 523, 656, 891, 658 is 1
