GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(814, 656) = 266992
GCD(814, 656) = ( 814 x 656 ) / 266992
= 814 / 656
= 814
Step2:
LCM(2, 978) = 978
GCD(2, 978) = ( 2 x 978 ) / 978
= 2 / 978
= 2
Step3:
LCM(2, 765) = 1530
GCD(2, 765) = ( 2 x 765 ) / 1530
= 2 / 765
= 2
So, Greatest Common Divisor of 814, 656, 978, 765 is 1
