Given numbers are 788, 189, 660, 578
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(788, 189) = 148932
GCD(788, 189) = ( 788 x 189 ) / 148932
= 788 / 189
= 788
Step2:
LCM(1, 660) = 660
GCD(1, 660) = ( 1 x 660 ) / 660
= 1 / 660
= 1
Step3:
LCM(1, 578) = 578
GCD(1, 578) = ( 1 x 578 ) / 578
= 1 / 578
= 1
So, Greatest Common Divisor of 788, 189, 660, 578 is 1
