GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(978, 158) = 77262
GCD(978, 158) = ( 978 x 158 ) / 77262
= 978 / 158
= 978
Step2:
LCM(2, 139) = 278
GCD(2, 139) = ( 2 x 139 ) / 278
= 2 / 139
= 2
Step3:
LCM(1, 999) = 999
GCD(1, 999) = ( 1 x 999 ) / 999
= 1 / 999
= 1
So, Greatest Common Divisor of 978, 158, 139, 999 is 1
