Given numbers are 387, 154, 840, 459
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(387, 154) = 59598
GCD(387, 154) = ( 387 x 154 ) / 59598
= 387 / 154
= 387
Step2:
LCM(1, 840) = 840
GCD(1, 840) = ( 1 x 840 ) / 840
= 1 / 840
= 1
Step3:
LCM(1, 459) = 459
GCD(1, 459) = ( 1 x 459 ) / 459
= 1 / 459
= 1
So, Greatest Common Divisor of 387, 154, 840, 459 is 1
