Given numbers are 402, 669, 857, 530
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(402, 669) = 89646
GCD(402, 669) = ( 402 x 669 ) / 89646
= 402 / 669
= 402
Step2:
LCM(3, 857) = 2571
GCD(3, 857) = ( 3 x 857 ) / 2571
= 3 / 857
= 3
Step3:
LCM(1, 530) = 530
GCD(1, 530) = ( 1 x 530 ) / 530
= 1 / 530
= 1
So, Greatest Common Divisor of 402, 669, 857, 530 is 1
