Given numbers are 530, 207, 908, 861
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(530, 207) = 109710
GCD(530, 207) = ( 530 x 207 ) / 109710
= 530 / 207
= 530
Step2:
LCM(1, 908) = 908
GCD(1, 908) = ( 1 x 908 ) / 908
= 1 / 908
= 1
Step3:
LCM(1, 861) = 861
GCD(1, 861) = ( 1 x 861 ) / 861
= 1 / 861
= 1
So, Greatest Common Divisor of 530, 207, 908, 861 is 1
