Given numbers are 459, 387, 680, 512
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(459, 387) = 19737
GCD(459, 387) = ( 459 x 387 ) / 19737
= 459 / 387
= 459
Step2:
LCM(9, 680) = 6120
GCD(9, 680) = ( 9 x 680 ) / 6120
= 9 / 680
= 9
Step3:
LCM(1, 512) = 512
GCD(1, 512) = ( 1 x 512 ) / 512
= 1 / 512
= 1
So, Greatest Common Divisor of 459, 387, 680, 512 is 1
