Given numbers are 868, 248, 720, 613

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

Apply this formula for all numbers.

Step1:

LCM(868, 248) = 1736

GCD(868, 248) = ( 868 x 248 ) / 1736

= 868 / 248

= 868

Step2:

LCM(124, 720) = 22320

GCD(124, 720) = ( 124 x 720 ) / 22320

= 124 / 720

= 124

Step3:

LCM(4, 613) = 2452

GCD(4, 613) = ( 4 x 613 ) / 2452

= 4 / 613

= 4

So, Greatest Common Divisor of 868, 248, 720, 613 is 1
