Given numbers are 978, 809, 146, 634
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(978, 809) = 791202
GCD(978, 809) = ( 978 x 809 ) / 791202
= 978 / 809
= 978
Step2:
LCM(1, 146) = 146
GCD(1, 146) = ( 1 x 146 ) / 146
= 1 / 146
= 1
Step3:
LCM(1, 634) = 634
GCD(1, 634) = ( 1 x 634 ) / 634
= 1 / 634
= 1
So, Greatest Common Divisor of 978, 809, 146, 634 is 1
