Given numbers are 628, 189, 516, 102

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

Apply this formula for all numbers.

Step1:

LCM(628, 189) = 118692

GCD(628, 189) = ( 628 x 189 ) / 118692

= 628 / 189

= 628

Step2:

LCM(1, 516) = 516

GCD(1, 516) = ( 1 x 516 ) / 516

= 1 / 516

= 1

Step3:

LCM(1, 102) = 102

GCD(1, 102) = ( 1 x 102 ) / 102

= 1 / 102

= 1

So, Greatest Common Divisor of 628, 189, 516, 102 is 1
