GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(387, 424) = 164088
GCD(387, 424) = ( 387 x 424 ) / 164088
= 387 / 424
= 387
Step2:
LCM(1, 852) = 852
GCD(1, 852) = ( 1 x 852 ) / 852
= 1 / 852
= 1
Step3:
LCM(1, 728) = 728
GCD(1, 728) = ( 1 x 728 ) / 728
= 1 / 728
= 1
So, Greatest Common Divisor of 387, 424, 852, 728 is 1
