Given numbers are 621, 670, 128, 886

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

Apply this formula for all numbers.

Step1:

LCM(621, 670) = 416070

GCD(621, 670) = ( 621 x 670 ) / 416070

= 621 / 670

= 621

Step2:

LCM(1, 128) = 128

GCD(1, 128) = ( 1 x 128 ) / 128

= 1 / 128

= 1

Step3:

LCM(1, 886) = 886

GCD(1, 886) = ( 1 x 886 ) / 886

= 1 / 886

= 1

So, Greatest Common Divisor of 621, 670, 128, 886 is 1
