GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(308, 978) = 150612
GCD(308, 978) = ( 308 x 978 ) / 150612
= 308 / 978
= 308
Step2:
LCM(2, 814) = 814
GCD(2, 814) = ( 2 x 814 ) / 814
= 2 / 814
= 2
Step3:
LCM(2, 787) = 1574
GCD(2, 787) = ( 2 x 787 ) / 1574
= 2 / 787
= 2
So, Greatest Common Divisor of 308, 978, 814, 787 is 1
