Given numbers are 978, 476, 940, 717
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(978, 476) = 232764
GCD(978, 476) = ( 978 x 476 ) / 232764
= 978 / 476
= 978
Step2:
LCM(2, 940) = 940
GCD(2, 940) = ( 2 x 940 ) / 940
= 2 / 940
= 2
Step3:
LCM(2, 717) = 1434
GCD(2, 717) = ( 2 x 717 ) / 1434
= 2 / 717
= 2
So, Greatest Common Divisor of 978, 476, 940, 717 is 1
