Given numbers are 651, 210, 173, 530
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(651, 210) = 6510
GCD(651, 210) = ( 651 x 210 ) / 6510
= 651 / 210
= 651
Step2:
LCM(21, 173) = 3633
GCD(21, 173) = ( 21 x 173 ) / 3633
= 21 / 173
= 21
Step3:
LCM(1, 530) = 530
GCD(1, 530) = ( 1 x 530 ) / 530
= 1 / 530
= 1
So, Greatest Common Divisor of 651, 210, 173, 530 is 1
