Given numbers are 189, 307, 661, 710
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(189, 307) = 58023
GCD(189, 307) = ( 189 x 307 ) / 58023
= 189 / 307
= 189
Step2:
LCM(1, 661) = 661
GCD(1, 661) = ( 1 x 661 ) / 661
= 1 / 661
= 1
Step3:
LCM(1, 710) = 710
GCD(1, 710) = ( 1 x 710 ) / 710
= 1 / 710
= 1
So, Greatest Common Divisor of 189, 307, 661, 710 is 1
