GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(390, 606) = 39390
GCD(390, 606) = ( 390 x 606 ) / 39390
= 390 / 606
= 390
Step2:
LCM(6, 528) = 528
GCD(6, 528) = ( 6 x 528 ) / 528
= 6 / 528
= 6
Step3:
LCM(6, 556) = 1668
GCD(6, 556) = ( 6 x 556 ) / 1668
= 6 / 556
= 6
So, Greatest Common Divisor of 390, 606, 528, 556 is 2
