Given numbers are 557, 391, 637, 835

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

Apply this formula for all numbers.

Step1:

LCM(557, 391) = 217787

GCD(557, 391) = ( 557 x 391 ) / 217787

= 557 / 391

= 557

Step2:

LCM(1, 637) = 637

GCD(1, 637) = ( 1 x 637 ) / 637

= 1 / 637

= 1

Step3:

LCM(1, 835) = 835

GCD(1, 835) = ( 1 x 835 ) / 835

= 1 / 835

= 1

So, Greatest Common Divisor of 557, 391, 637, 835 is 1
