Given numbers are 628, 660, 879, 660

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

Apply this formula for all numbers.

Step1:

LCM(628, 660) = 103620

GCD(628, 660) = ( 628 x 660 ) / 103620

= 628 / 660

= 628

Step2:

LCM(4, 879) = 3516

GCD(4, 879) = ( 4 x 879 ) / 3516

= 4 / 879

= 4

Step3:

LCM(1, 660) = 660

GCD(1, 660) = ( 1 x 660 ) / 660

= 1 / 660

= 1

So, Greatest Common Divisor of 628, 660, 879, 660 is 1
