Given numbers are 667, 640, 521, 428
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(667, 640) = 426880
GCD(667, 640) = ( 667 x 640 ) / 426880
= 667 / 640
= 667
Step2:
LCM(1, 521) = 521
GCD(1, 521) = ( 1 x 521 ) / 521
= 1 / 521
= 1
Step3:
LCM(1, 428) = 428
GCD(1, 428) = ( 1 x 428 ) / 428
= 1 / 428
= 1
So, Greatest Common Divisor of 667, 640, 521, 428 is 1
