Given numbers are 660, 652, 570, 990
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(660, 652) = 107580
GCD(660, 652) = ( 660 x 652 ) / 107580
= 660 / 652
= 660
Step2:
LCM(4, 570) = 1140
GCD(4, 570) = ( 4 x 570 ) / 1140
= 4 / 570
= 4
Step3:
LCM(2, 990) = 990
GCD(2, 990) = ( 2 x 990 ) / 990
= 2 / 990
= 2
So, Greatest Common Divisor of 660, 652, 570, 990 is 2
