GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(978, 665) = 650370
GCD(978, 665) = ( 978 x 665 ) / 650370
= 978 / 665
= 978
Step2:
LCM(1, 406) = 406
GCD(1, 406) = ( 1 x 406 ) / 406
= 1 / 406
= 1
Step3:
LCM(1, 186) = 186
GCD(1, 186) = ( 1 x 186 ) / 186
= 1 / 186
= 1
So, Greatest Common Divisor of 978, 665, 406, 186 is 1
