Given numbers are 389, 270, 157, 250
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(389, 270) = 105030
GCD(389, 270) = ( 389 x 270 ) / 105030
= 389 / 270
= 389
Step2:
LCM(1, 157) = 157
GCD(1, 157) = ( 1 x 157 ) / 157
= 1 / 157
= 1
Step3:
LCM(1, 250) = 250
GCD(1, 250) = ( 1 x 250 ) / 250
= 1 / 250
= 1
So, Greatest Common Divisor of 389, 270, 157, 250 is 1
