Given numbers are 557, 691, 820, 641

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

Apply this formula for all numbers.

Step1:

LCM(557, 691) = 384887

GCD(557, 691) = ( 557 x 691 ) / 384887

= 557 / 691

= 557

Step2:

LCM(1, 820) = 820

GCD(1, 820) = ( 1 x 820 ) / 820

= 1 / 820

= 1

Step3:

LCM(1, 641) = 641

GCD(1, 641) = ( 1 x 641 ) / 641

= 1 / 641

= 1

So, Greatest Common Divisor of 557, 691, 820, 641 is 1
