Given numbers are 305, 641, 520, 190
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(305, 641) = 195505
GCD(305, 641) = ( 305 x 641 ) / 195505
= 305 / 641
= 305
Step2:
LCM(1, 520) = 520
GCD(1, 520) = ( 1 x 520 ) / 520
= 1 / 520
= 1
Step3:
LCM(1, 190) = 190
GCD(1, 190) = ( 1 x 190 ) / 190
= 1 / 190
= 1
So, Greatest Common Divisor of 305, 641, 520, 190 is 1
