GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(652, 388) = 63244
GCD(652, 388) = ( 652 x 388 ) / 63244
= 652 / 388
= 652
Step2:
LCM(4, 390) = 780
GCD(4, 390) = ( 4 x 390 ) / 780
= 4 / 390
= 4
Step3:
LCM(2, 689) = 1378
GCD(2, 689) = ( 2 x 689 ) / 1378
= 2 / 689
= 2
So, Greatest Common Divisor of 652, 388, 390, 689 is 1
