GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(189, 145) = 27405
GCD(189, 145) = ( 189 x 145 ) / 27405
= 189 / 145
= 189
Step2:
LCM(1, 483) = 483
GCD(1, 483) = ( 1 x 483 ) / 483
= 1 / 483
= 1
Step3:
LCM(1, 520) = 520
GCD(1, 520) = ( 1 x 520 ) / 520
= 1 / 520
= 1
So, Greatest Common Divisor of 189, 145, 483, 520 is 1
