Given numbers are 481, 388, 840, 190
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(481, 388) = 186628
GCD(481, 388) = ( 481 x 388 ) / 186628
= 481 / 388
= 481
Step2:
LCM(1, 840) = 840
GCD(1, 840) = ( 1 x 840 ) / 840
= 1 / 840
= 1
Step3:
LCM(1, 190) = 190
GCD(1, 190) = ( 1 x 190 ) / 190
= 1 / 190
= 1
So, Greatest Common Divisor of 481, 388, 840, 190 is 1
