Given numbers are 580, 129, 861, 530
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(580, 129) = 74820
GCD(580, 129) = ( 580 x 129 ) / 74820
= 580 / 129
= 580
Step2:
LCM(1, 861) = 861
GCD(1, 861) = ( 1 x 861 ) / 861
= 1 / 861
= 1
Step3:
LCM(1, 530) = 530
GCD(1, 530) = ( 1 x 530 ) / 530
= 1 / 530
= 1
So, Greatest Common Divisor of 580, 129, 861, 530 is 1
