GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(390, 872) = 170040
GCD(390, 872) = ( 390 x 872 ) / 170040
= 390 / 872
= 390
Step2:
LCM(2, 548) = 548
GCD(2, 548) = ( 2 x 548 ) / 548
= 2 / 548
= 2
Step3:
LCM(2, 922) = 922
GCD(2, 922) = ( 2 x 922 ) / 922
= 2 / 922
= 2
So, Greatest Common Divisor of 390, 872, 548, 922 is 2
