Given numbers are 780, 256, 189, 483
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(780, 256) = 49920
GCD(780, 256) = ( 780 x 256 ) / 49920
= 780 / 256
= 780
Step2:
LCM(4, 189) = 756
GCD(4, 189) = ( 4 x 189 ) / 756
= 4 / 189
= 4
Step3:
LCM(1, 483) = 483
GCD(1, 483) = ( 1 x 483 ) / 483
= 1 / 483
= 1
So, Greatest Common Divisor of 780, 256, 189, 483 is 1
