Given numbers are 308, 114, 518, 620
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(308, 114) = 17556
GCD(308, 114) = ( 308 x 114 ) / 17556
= 308 / 114
= 308
Step2:
LCM(2, 518) = 518
GCD(2, 518) = ( 2 x 518 ) / 518
= 2 / 518
= 2
Step3:
LCM(2, 620) = 620
GCD(2, 620) = ( 2 x 620 ) / 620
= 2 / 620
= 2
So, Greatest Common Divisor of 308, 114, 518, 620 is 2
