GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(388, 664) = 64408
GCD(388, 664) = ( 388 x 664 ) / 64408
= 388 / 664
= 388
Step2:
LCM(4, 652) = 652
GCD(4, 652) = ( 4 x 652 ) / 652
= 4 / 652
= 4
Step3:
LCM(4, 308) = 308
GCD(4, 308) = ( 4 x 308 ) / 308
= 4 / 308
= 4
So, Greatest Common Divisor of 388, 664, 652, 308 is 4
