Given numbers are 628, 212, 557, 381

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

Apply this formula for all numbers.

Step1:

LCM(628, 212) = 33284

GCD(628, 212) = ( 628 x 212 ) / 33284

= 628 / 212

= 628

Step2:

LCM(4, 557) = 2228

GCD(4, 557) = ( 4 x 557 ) / 2228

= 4 / 557

= 4

Step3:

LCM(1, 381) = 381

GCD(1, 381) = ( 1 x 381 ) / 381

= 1 / 381

= 1

So, Greatest Common Divisor of 628, 212, 557, 381 is 1
