GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(978, 777) = 253302
GCD(978, 777) = ( 978 x 777 ) / 253302
= 978 / 777
= 978
Step2:
LCM(3, 606) = 606
GCD(3, 606) = ( 3 x 606 ) / 606
= 3 / 606
= 3
Step3:
LCM(3, 657) = 657
GCD(3, 657) = ( 3 x 657 ) / 657
= 3 / 657
= 3
So, Greatest Common Divisor of 978, 777, 606, 657 is 3
