GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(644, 564) = 90804
GCD(644, 564) = ( 644 x 564 ) / 90804
= 644 / 564
= 644
Step2:
LCM(4, 958) = 1916
GCD(4, 958) = ( 4 x 958 ) / 1916
= 4 / 958
= 4
Step3:
LCM(2, 220) = 220
GCD(2, 220) = ( 2 x 220 ) / 220
= 2 / 220
= 2
So, Greatest Common Divisor of 644, 564, 958, 220 is 2
