GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(660, 628) = 103620
GCD(660, 628) = ( 660 x 628 ) / 103620
= 660 / 628
= 660
Step2:
LCM(4, 128) = 128
GCD(4, 128) = ( 4 x 128 ) / 128
= 4 / 128
= 4
Step3:
LCM(4, 564) = 564
GCD(4, 564) = ( 4 x 564 ) / 564
= 4 / 564
= 4
So, Greatest Common Divisor of 660, 628, 128, 564 is 4
