Given numbers are 686, 392, 124, 741

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

Apply this formula for all numbers.

Step1:

LCM(686, 392) = 2744

GCD(686, 392) = ( 686 x 392 ) / 2744

= 686 / 392

= 686

Step2:

LCM(98, 124) = 6076

GCD(98, 124) = ( 98 x 124 ) / 6076

= 98 / 124

= 98

Step3:

LCM(2, 741) = 1482

GCD(2, 741) = ( 2 x 741 ) / 1482

= 2 / 741

= 2

So, Greatest Common Divisor of 686, 392, 124, 741 is 1
