Given numbers are 558, 621, 838, 357

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

Apply this formula for all numbers.

Step1:

LCM(558, 621) = 38502

GCD(558, 621) = ( 558 x 621 ) / 38502

= 558 / 621

= 558

Step2:

LCM(9, 838) = 7542

GCD(9, 838) = ( 9 x 838 ) / 7542

= 9 / 838

= 9

Step3:

LCM(1, 357) = 357

GCD(1, 357) = ( 1 x 357 ) / 357

= 1 / 357

= 1

So, Greatest Common Divisor of 558, 621, 838, 357 is 1
