Given numbers are 640, 667, 876, 242
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(640, 667) = 426880
GCD(640, 667) = ( 640 x 667 ) / 426880
= 640 / 667
= 640
Step2:
LCM(1, 876) = 876
GCD(1, 876) = ( 1 x 876 ) / 876
= 1 / 876
= 1
Step3:
LCM(1, 242) = 242
GCD(1, 242) = ( 1 x 242 ) / 242
= 1 / 242
= 1
So, Greatest Common Divisor of 640, 667, 876, 242 is 1
