Given numbers are 658, 428, 719, 691

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

Apply this formula for all numbers.

Step1:

LCM(658, 428) = 140812

GCD(658, 428) = ( 658 x 428 ) / 140812

= 658 / 428

= 658

Step2:

LCM(2, 719) = 1438

GCD(2, 719) = ( 2 x 719 ) / 1438

= 2 / 719

= 2

Step3:

LCM(1, 691) = 691

GCD(1, 691) = ( 1 x 691 ) / 691

= 1 / 691

= 1

So, Greatest Common Divisor of 658, 428, 719, 691 is 1
