GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(390, 190) = 7410
GCD(390, 190) = ( 390 x 190 ) / 7410
= 390 / 190
= 390
Step2:
LCM(10, 676) = 3380
GCD(10, 676) = ( 10 x 676 ) / 3380
= 10 / 676
= 10
Step3:
LCM(2, 650) = 650
GCD(2, 650) = ( 2 x 650 ) / 650
= 2 / 650
= 2
So, Greatest Common Divisor of 390, 190, 676, 650 is 2
