Given numbers are 677, 387, 330, 428
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(677, 387) = 261999
GCD(677, 387) = ( 677 x 387 ) / 261999
= 677 / 387
= 677
Step2:
LCM(1, 330) = 330
GCD(1, 330) = ( 1 x 330 ) / 330
= 1 / 330
= 1
Step3:
LCM(1, 428) = 428
GCD(1, 428) = ( 1 x 428 ) / 428
= 1 / 428
= 1
So, Greatest Common Divisor of 677, 387, 330, 428 is 1
