Given numbers are 620, 472, 644, 530

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

Apply this formula for all numbers.

Step1:

LCM(620, 472) = 73160

GCD(620, 472) = ( 620 x 472 ) / 73160

= 620 / 472

= 620

Step2:

LCM(4, 644) = 644

GCD(4, 644) = ( 4 x 644 ) / 644

= 4 / 644

= 4

Step3:

LCM(4, 530) = 1060

GCD(4, 530) = ( 4 x 530 ) / 1060

= 4 / 530

= 4

So, Greatest Common Divisor of 620, 472, 644, 530 is 2
