GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(867, 957) = 276573
GCD(867, 957) = ( 867 x 957 ) / 276573
= 867 / 957
= 867
Step2:
LCM(3, 978) = 978
GCD(3, 978) = ( 3 x 978 ) / 978
= 3 / 978
= 3
Step3:
LCM(3, 457) = 1371
GCD(3, 457) = ( 3 x 457 ) / 1371
= 3 / 457
= 3
So, Greatest Common Divisor of 867, 957, 978, 457 is 1
