Given numbers are 481, 375, 155, 687
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(481, 375) = 180375
GCD(481, 375) = ( 481 x 375 ) / 180375
= 481 / 375
= 481
Step2:
LCM(1, 155) = 155
GCD(1, 155) = ( 1 x 155 ) / 155
= 1 / 155
= 1
Step3:
LCM(1, 687) = 687
GCD(1, 687) = ( 1 x 687 ) / 687
= 1 / 687
= 1
So, Greatest Common Divisor of 481, 375, 155, 687 is 1
