Given numbers are 628, 842, 670, 513

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

Apply this formula for all numbers.

Step1:

LCM(628, 842) = 264388

GCD(628, 842) = ( 628 x 842 ) / 264388

= 628 / 842

= 628

Step2:

LCM(2, 670) = 670

GCD(2, 670) = ( 2 x 670 ) / 670

= 2 / 670

= 2

Step3:

LCM(2, 513) = 1026

GCD(2, 513) = ( 2 x 513 ) / 1026

= 2 / 513

= 2

So, Greatest Common Divisor of 628, 842, 670, 513 is 1
