Given numbers are 612, 644, 620, 558

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

Apply this formula for all numbers.

Step1:

LCM(612, 644) = 98532

GCD(612, 644) = ( 612 x 644 ) / 98532

= 612 / 644

= 612

Step2:

LCM(4, 620) = 620

GCD(4, 620) = ( 4 x 620 ) / 620

= 4 / 620

= 4

Step3:

LCM(4, 558) = 1116

GCD(4, 558) = ( 4 x 558 ) / 1116

= 4 / 558

= 4

So, Greatest Common Divisor of 612, 644, 620, 558 is 2
