GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(657, 662) = 434934
GCD(657, 662) = ( 657 x 662 ) / 434934
= 657 / 662
= 657
Step2:
LCM(1, 867) = 867
GCD(1, 867) = ( 1 x 867 ) / 867
= 1 / 867
= 1
Step3:
LCM(1, 978) = 978
GCD(1, 978) = ( 1 x 978 ) / 978
= 1 / 978
= 1
So, Greatest Common Divisor of 657, 662, 867, 978 is 1
